    New question here. which MCE optics will win

    Which optic is going to be the killer that every one will want

    and which optic maker is going to nail the issues so a 5 degree spot is just that
    not a 12 degree 4 leaf clover .

    and a 10 degree medium is not a 20 degree flood

    I'm betting on the Ledil EVA and LM1...

    Ah, that's the $6.40 question. Based upon no evidence whatsoever, I'm guessing the current crop of 26mm optics won't cut the mustard, due to the spacing of MC-E's 4 dice. So I'm keen to see how Ledil's EVA performs.

    I have a ledil LM1 and will eventually post beam shots when I finish the light. I went with the soothe spot. Its a very nice clean beam but not all that spotty. I am a little worried its not going to be that great on my helmet. Guess I have to finish the light to find out. One thing about the LM1 that's really disappointing is that the lens is new for the MC-E but the holder is for the XP-E and snaps on to the XP-E, it dosnt snap onto my MC-E and just sits there and will have to be glued. I am still holding out hope for the boomerang reflector and kind of wishing I had gone that route. Of course with out really nice glass all the extra efficiency is killed by the window that covers the front.

    Yeah, I'm holding a huge hope for the Boomerang reflectors, but 10 degrees is the tightest they come in, so I'm not sure how well that will work out. Then again, not too much more spread out than my 6 degree spot... and with a lot more punch and power I would hope.

    Just finished up trying a couple of ledil mc-e optics. I ordered the CMC-D and the CMC-M. My dual Q5 light head uses the XR-E equivalent CMC-D but on the MC-E the spread is noticeably wider. Almost like the XR-E Ledil -M optic. I think I need the smooth spot to compliment the -D optic. The beam is wider than I prefer. However, I was very impressed with the uniformity. Nice smooth wall of light.

    I setup a dual MC-E (K BIN) and ran it off a 16 volt battery and a 3023-1000 Buck. On each chip the leds were in series but each chip in parallel to one another so I was only driving around .45amps into each led. I estimate a little over 800 Lumens. Quite a bit more light than the dual Q5 setup. Interesting, I can feel more heat on my hand when I place it in the beam path than on the dual Q5 light.

    Dual MC-E > 2(14v x .45A) = 12.6 watts
    Dual Q5 > 2(3.5v x .9A) = 6.3 watts

    Gonna be a challenge to dissipate all that heat..

    I'll try to get a pic soon. I haven't put the thing in one of my cases but I was impressed enough to order more leds (m bin). This time on a series configured star.

    Don't have optics yet, but was playing with my MC-E. I mounted it to a series-wired star and temporarily fixed it to a 5lb cast weight (super sized heat sink) with some thermal paste. The only other bare emitter I have is a Cree P4 (I think), so I set it up the same way (its nice to have a dual channel power supply).

    Running at 500mA, the MC-E is BLINDING!! I still have spots floating in my eyes! It made the P4 look old and dim.

    Can't wait to get some optics to try. This thing ROCKS!

    Also, (and I mentioned this somewhere else) the Vf is closer to 12.5V when all four dice are wired in series...

    Mr Trout mentioned this from his optic testing rig also. Very useful information for people like me who only have 14.8v packs!

    Yes the Vf is lower on the newer LEDs. Im measuring around 3.3v at 1A on new R2s.

    Anyone notice the promising MCE optics are getting about as big as the MR11???

    I really don't have a problem with that. Right now I've got a triple Q5 setup that is MR11 sized. It actually would be kind of nice to have the single MC-E fit in the same housing, as I wouldn't have to design a new one. Downside is the bulk for a single emitter... But with Trout's idea of the housing that wraps around the bar, we could make the whole housing smaller dia, and flare the end to fit the optic.

    Yes the lower VF`s is good news .

    The wow factor is not there with the mce with the messing about I have done .
    and the small is beautifull has not happened yet also .

    I went out for a ride yesterday in the dark with the triple K bin stem light / the single M bin mini trout light and a quad R2 helmet light .

    I was disapointed with the beams from the MCE`s
    but happy with the quantity of light .

    but the quad cutter optic which I believe to be a ledil cute was the better beam .


    The jury is still out

    one think that stood out was the single M bin MCE could make a difference in the beam from the 3 Kbin MCE and they were all on the same optic

    Ledil LM1 optic

    Finishing up the last details on my MC-E helmet light right now. Running at 400ma, I think I need to turn it down a bit, getting very hot. Of course this is just still air testing. Tons of light out of this thing and what a nice color. I also report a low VF.
    The ledil LM1 optic
    Where to start.......
    The holder I recieved is clearly meant for the XR-E.
    It fits perfectly around the XR-E and actually snaps into place. WIth my MC-E it just sort of sits there and provides no real help in centering the optic. Maybe thats my problem, maybe the optic is just not centered. Also the opening in the bottom of the optic is not large enough to fir totally over the MC-E dome.
    The beam is not nice at all.
    Not very tight, looks to be way more than the +-10 advertised.
    It has a donut in the center and I cant eat it. Pure rubbish. The donut is noticable and the spill is a flower pattern. Quite dissapointing. I better keep looking for a better optic or place some orders for reflectors. As a helmet light this is not going to cut it I am affraid.
    I will be trying the secondary optic made by cree for the XR-E next. Hopefully it wont suck.

    That is disapointing news is that another optic to cross of the wish list .

    will we get any pics of the build and beam anytime .

    Well after a lot of swearing at it I pried the optic holder up and re-glued it and the donut hole seems to have gone away but all the other complaints still stand. I hope other MC-E optic holders are better and actually center the thing, an optic holder that dosnt self center is about as useful as a non alcaholic beer...
    I turned down the drive current to 300ma since this thing is dinotte sized and got real hot in still air testing. Going out tonite for a little ride tonite and will report back on how it does. Photos coming eventually, but this is one for the ugly thread for sure.

    I also building an MCE helmet light and I have to say the optic issue is killing everyone.
    I'm putting my build on hold for a while until either the Boomerang reflectors or some other good optic hits the market. I tried some reflectors I have and they're all terrible, with the dreaded donut. I'm not an optic expert so I'm scratching a hole in my head.
    I did get an email from Cutter and they are processing my Carclo 20mm optic order finally, maybe that will solve this issue...
    I just don't know if the optics will be tight enough, I ordered the frosted narrow(18') and medium(24') as well as an oval beam, I'll keep you guys posted.

    I'm building yet another Dinotte-style MC-E helmet-light. Was poised to 'pull the trigger' and order a couple of different Carclo 26.5mm optics to try out, but after reading Bikerjay's tail of woe I'm hesitating now. Ah, what the heck, somebody has to be an early adopter I guess.

    The Carclo 26.5 tight was not bad in my testing

    but the best one so far imho is a modded ledil xre Rocket SS
    Which is going in to a mates light at the moment .





    sadly I forgot to take a photo of before mod and after and it is now glued in the light .

    What sort of modding did you do, it has an odd looking base, did you just open up the base a little so it fits over the mc-e. Or did you have to sand down the base or cut it totally off. I would think the base would get in the way of all the wires necessary for a series wired mc-e.
    Also is the thing really 26mm in diameter. Maybe I will have to make a better housing eventually with a 26mm Inner diameter unless it could be some how made to fit my 22.2mm inner diameter housing. That ledil rocket SS lens sure does look nice.

    should have taken pics but didnt really expect it to be any good

    first off I dremeled the wings off so it would clear the solder pads and spaggetti of the series wired star .

    that is when I took the first beam shot .

    then while I was inspecting it under a magnifier I saw that about 1 mm of mce dome was visibly from the side . so then sanded the base flat so the dome was totally inside the optic .
    the end result is total removal of the base to leave a standard shaped optic
    which sits over the dome of the mce nicely but then needs to be fixed in the housing
    mine will have a clear disk glued in front to hold it all together .

    beamshot in the next couple of days of the finished light

    Yes it is 26 mm

    Just tried the Polymer Optic 185 and it is a nice smooth beam with no clover. It is a wide pattern although I am very happy with it overall and will probably go this direction. Not happy with the Fraen narrow optic or reflector as they both have rings, although the reflector seems to have more throw. It is kind of hard to tell though with that much light right in front of you how the throw really is for me at least.

    P S A For All Those Waiting For Optics

    For all you out there waiting for orders for optics or optics and leds then the agony may be over soon

    I just had a reply from Mark at Cutters Who sends his apologies for the waiting to all of you out there .

    Hi Chris

    Verbatim, my last email from Ledil on Monday the 3rd



    ''LM1 and BOOM are ready.

    Also LC1 with tape, LXP with tape and CXP with tape.

    I have samples of EVA and if they are OK (will measure on Tuesday), we can start molding them as well.

    In addition we have TINA-XP ready

    TWIDDLE-XRE will be ready in 2 weeks.

    The same for CMC.''

    I had expected this to all be done a month ago, so my apologies but outside our control

    Cheers

    Mark

    Thanks for the update. I'm waiting on two Ledil Boom reflectors and two MC-E from cutter. Will post results as soon as I get them in my hands and get thinks up and running.

    I am really starting to wonder if the LM1 i received is actually an LC1. They look to be nearly identical. Maybe there is hope for the LM1 after all.

    Cant wait too see the boomerang, it should fit in my housing and if they look nice Ill have to get a hold of one.

    The CMC is what we are all waiting for I think. It would be great to see a aches alot tripple with 3 MCE running at 300ma. Could easily be a 1000lumen monster. Should be way brighter and more efficient than 3 R2 at 1A. Maybe even better than 4 R2 at 700ma.

    what about an MR16 triple @ 600ma

    As I have 3 mce and no proper optics I was messing about today
    and found this in the parts bin so why not give it a try .

    most likley be a flood monster as it is a wide optic.




    now I have to wait for the darkness to find out .

    kahtod cree medium...

    troutie, I was playing w/ that exact optic on an mc-e. I think it's a 25 deg optic. It produces a nice wide beam w/ no artifacts I could see. I prefer a more narrow beam, so I tried the kahtod triple narrow (8 deg I think)...but the beam wasn't so good. I only had 1 mc-e at the time...so maybe w/ 3 on it would be better.

    That's great news. Perhaps I can build my light over the x-mas break [between trips to the pub, of course].

    I'm confused:

    "The same for CMC"



    Then what has Cutter been shipping? I ordered CMC Ledil optics and recieved them last week. Thought they look too similiar to the XR-E optics... And I wasn't too thrilled with their performance.

    First I get the wrong LED bins and now what I suspected about the optics is probably true. My trust in Cutter to ship what he says is beginning to diminish.

    I think I'll go build some R2 lights and wait till the MC-E dust settles.

    the LC1 will definatly not even go over the dome on a MCE

    You probable have some pre production ones
    but if you have RS or SS then post some beam shots if you can as I have beamshots
    from the xre versions with an mce to compare with.

    I've only got some Carclo 26,5mm lenses, and I think they look good.

    Tried them vs an old 3 x Cree (not sure which bin, but not the newest ones..) with Ledil CRS lenses (1 x 9 deg and 2 x 15 deg I think):

    3 x XR-E @1000mA


    Cree MC-E @ 1000mA w/18 deg Carclo 26,5mm lens:


    Really looking forward to trying the Boom reflectors. Hoping they will give a Tesla-ish beam pattern!

    Needless to say - @1A the alu-pipe mounted to the MC-E got VERY hot.

    About my LM1 I received a while ago.
    The holder is for the XR-E I think, since it just sits on top of my mce and does not center the thing or snap onto the outside of the emitter. When I put the holder on to a XR-E it snaps to the out side of it and centers it self quite well. However the data sheets show photos and list measurements that look identical so maybe they are the same. Also If i take just the optic and place it over my MC-E the thing does not fit over the dome. On the the other hand the photos on the Ledil website show that the optic for the LM1 is faceted not frosted where is the LC1 is frosted. Based on this and the dimensions on the data sheet being the same I think I did get the LM1 and its just a pre-production or pre release and the will soon be released in greater numbers. It would be nice if the optic holder centered it self. I am starting to think Ledil is just selling warmed over XR-E optics and a few happen to work well.

    Darkness came and with it the rain but in true light builders spirit I did not let a little rain get in the way of a beamshot .

    this is the triple MR16 wide optic with 3 MCE @ 600ma

    HI / LO




    And for a comparison now it is built in to a light and also because I like it
    The modded ledil rocket ss



    Quite impressive and a huge ammount of light from the triple but there is a down side
    the heat build upin the block of ali was quite fast so would present a challenge for a light housing MR16 sized .


    I would like to try the narrower options for this optic as a Betty beater

    I recall I had some pre production samples but had not tested them myself, if they are not good, shoot them back to us and I will replace with the production models when available. We are provided with lots of optics in pre production form and typically get rev2 in production, so my apologies

    Since you seemingly have time to post online in forums. How bout someone over there replying to my emails about where my order is?

    1. I dunno how it works in Aus, but you're not supposed to charge someone until you ship over here. I don't mind it a big deal if I know my stuff is going to arrive sometime soon, but I have no idea what is going on with my order with you guys. You have not responded to any of my emails, I can't track my order on your site and there has been a total lack of communication on your part.

    I'm extremely disappointed ordering from you, and so far I see no reason you've earned the recommendations of so many people online. As the cheap Chinese sites DX and Kai have both responded to my questions in a timely manner, and both have managed to ship complete orders to me already (with free shipping to boot!)

    So who do we have to contact over there to get a response?

    WOW Troutie!
    What battery are you running for that monster and what driver and settings?
    Do you think those beamshots represent what you were actually seeing or are they overexposed?

    I am not sure on the overexposed but when I did some beamshots a while ago
    it was suggested to use the MTBR standard settings for a camera

    which are F4 @ 6 seconds iso 100 -white balance -daylight

    so to keep it a level playing field these are the settings I use for all beamshots .

    The monster is 3 MCE K bin wired 6series 2 parallel
    maxflex @ 1200ma
    14.8 v li ion

    set up on that block of ali as a test bed

    Not worth the shipping charge to send them back. I just hope the new order I placed on 10/28 gets processed correctly. I also can't seem to get a reply to my emails. The order is 5955.

    Couple of M bin, WH tint MC-E leds mounted on a series pre-configured star and CMC optics. I'd really like this order to arrive with the right stuff.

    Hi Troutie,

    Wow, how did the triple MCE go? That looks a monster...

    I initially did not think the MCE's were much to write home about (I have a triple R2, Troutie housing which does very nicely, thankyou), but after doing some calcs on the M bins, they look very tasty. A triple MCE in a MR16 housing would run very well in theory, particularly at up to 13W. The 50mm housing should provide better cooling than my triple R2 (?) and might run ok up to 13W with a reasonable winter's breeze.

    Numbers from the cree data sheets, interpolated by eye from the graphs (come pretty close as cree claim 9.8W for 790lm and 0.7A). Run time based on a 71Whr battery I'm looking at. Mmmm. nice....

    Cheers

    I'm not sure if this has already been posted, but Ledil has updated their data sheets for the EVA and LM-1. No detailed diagrams, but they do have beam patterns for the EVA.

    Thanks for that Pinkrobe last time I looked there were no beam pics

    so they do exist then I hope they have made the trip to cutters then round to me in the UK .

    I wonder how far they will have traveled when I get mine .

    Lets hope they live up to expectations .

    Hi Peter
    You must have one of the first Troutie housings .


    That is a fair old commute . have you looked into a dynohub setup , seems to be the way to go for commuting
    the triple MCE may be a tad bright for the tarmac.

    Cheers Trout

    Hi Troutie,

    Yep, commute takes me between 1hr26 to 1hr 28 each way, its amazing how when you think you're cycling much harder so little difference is made to the cycle time. I'm using my full suss MTB (!!!) with 110psi road slicks, which make an enormous difference, although tis pretty bumpy/slippery on a rough gravel section I use. I'm eyeing up a proper road bike which will allow me to run my MTB for what its designed for this winter.

    High Lumens for the road are a definite must IMO, particulary on dark country lanes, with puddles and on coming cars when you doing >= 20mph. I looked at the dynohub, it's a good idea, but I reckon I'd still rather carry a LION battery and run 10W-15W worth of LEDs. Maybe a cutter R2 quad would be fine, but I also like the idea of oval optics and MCE's too....so I'm watching your current progress with great interest!

    Here's a link to my current trout light build (which is still running well), so it may well be a early ver of yours.

    In true Troutie impatience style I could not wait for the narrow triple optic to come from Cutters .
    so I thought why not see if I can lathe the difusing bobbles off the front of the medium optic
    it was a bit delicate to nip in the chuck but I managed and was quite suprised on how good it came out .
    after a few very light passes they were gone

    .

    then into the light and off to the bit of test trail I have been using .

    first up the shot from the un modded optic
    followed by the modded

    I do think there should be a revised camera setting for the new multi chip leds
    any camera experts on here to advise please .








    It does seem to have tightened the beam up a tad and if I had aimed it up the trail a bit more the hotspot would have lit up the trees in the far distance .

    next pics are stepping down the levels on the maxflex in multimode

    Now looking at the shots
    look at the first pic which is unmodded @ full power.

    and look at pics 3 and 4 which are 1 and 2 steps down in power on the Maxflex

    Hi Troutie,

    Very nice!
    Is that a stock MR11 XRE optic? What's "full power" - 700mA?

    Hi Peter it is a stock Kahtod MR16 triple optic for the XRE .

    sadly no full power is 600ma , untill the HipFlex comes out

    A bit of trial and error would be your best bet Troutie. I would probably start by changing one stop in aperture, ie going from f4 to f5.6 as it will effectively halve the amount of light hitting the sensor. That should:
    a) prevent blowing the highlights in the beam hotspot.
    b) Give a slightly wider depth of field which will make focus points less critical when trying to focus in the dark.

    what about the time , 6 seconds my camera s next setting is 4.5 secs
    what effect would that have .

    The goal is to have the shot look like what you see when riding

    it would seem that the camera setting can make a poor light look good

    do Lupine use a different setting than the MTBR ones

    Time is the other possibility, going from 6 to 4/4.5 seconds would yield a noticeable reduction in overall "brightness".

    I found that i had NFI where i was focussing with my weak little lights and was relying on depth of field to ensure that something was in focus.

    I did see reference to a different set of exposures in a thread here just the other day but I have no idea where it was.

    So which gives the most truthfull result

    smaller aperture or less time .

    what settings did you use for the Salty sock pics
    still makes me laugh socks on sticks in the middle of the night

    Troutie, I think Salty's right about a bit of trial-and-error being needed, since you're the one pushing the envelope here

    For example, I'd first try stopping down from f4 -> f5.6, which exactly halves the amount of light reaching the sensor. My gut-feeling is that'll probably give a nicely exposed beamshot.

    But failing that, try reducing the shutter-speed from 6sec -> 4.5sec instead. But bear in mind that 4.5s in not one of the 'standard' slow shutter-speeds available on most cameras ie. 1, 2 & 4seconds... Anyway, 4.5sec @f4 will reduce the light reaching the sensor by 33% (which is stiil probably a bit overexposed). Pls let us know what you discover.

    I thought your idea of using the MTBR settings was a good one and mirrored that for the socks on sticks. (as closely as possible, Max aperture i could get on the crap lens was 4.5).

    If you were to drop the exposure by half, increase the aperture by a stop, or drop the ISO by half... the results would be all but indistinguishable - less light hitting the sensor and a "darker" looking pic.

    In all honesty, the only way you will be able to replicate what you are seeing is to take a couple with varied exposures and see what best replicates what you are seeing.

    I first said i would play with aperture first but it is more difficult to visualize what a change in aperture means to your overall exposure, so start by taking multiple pics at 3,4,5 secs and review them and see what you like.

    There is one small upside with faster shutter-speeds; a shorter shutter-speed will help minimize the risk of blur due to camera-shake. Of course, you'll still need a tripod, but the beamshots will tend to be sharper at the faster shutter-speed. Plus in some recent beamshots I saw plenty of blur due to the vegetation swaying wildly in the strong breeze, so that effect would be minimized as well.

    One last tip, for tripod pics you ideally want a remote shutter-release, otherwise pressing the shutter will cause the whole camera+tripod to shake (only a bit, but that's enough). But here's a good trick in case you don't have a fancy remote shutter-release:
    * Just set the camera's inbuilt self-timer (I like 2-seconds delay). In this way, pressing the shutter doesn't shake the camera 'cos the shutter doesn't fire until 2 seconds later

    Since your using a P&S start with playing with either the exposure time, or the aperture until you get something that looks correct in exposure.

    The more light you have, either the shorter your exposure should be, or the smaller your aperture should be (Bigger numbers since its a fraction).

    As well as aperture and exposure time, Salty did mention ISO (gain or amplification of the electrical signal from your camera's sensor). This is important - you need to choose a setting for this. Some camera's will use an auto ISO setting, and this will make comparisons very hard....The more gain (higher ISO value) the brighter the picture will be until it gets noisy (speckles). Expensive cameras like full frame SLRs will be able to go up ISO 12000 or more with out the speckle effects (thus allowing faster shutter speed and therefore less motion blur), but typical compacts will struggle with more than ISO 800. Thus I suggest IS0 100, 200 or 400, but you will need to try it on your camera.

    Cheers,
    Peter

    Just got a nice little envelope of the Ledil Boom reflectors in the mail
    Haven't fired them up yet, but it seems like they need a little trimming when I'm gonna mount them on my "spaghetti" MC-E from Cutter...

    After some very preliminary backyard testing with the narrow Boom reflector, I think I can say WOW. Without having seen a Tesla in real life, I think I can say that this is THE Tesla-killer.
    Very nice hotspot with LOTS of spill. A whole different beam-pattern than any lens I've tried. I guess that's the thing with reflectors - you can get both hotspot AND spill. With one if these on the helmet and one on the bars I'll be more than happy.

    Only thing is I didn't take any beamshots. This is why:


    (Shown with Carclo 26,5mm lens)

    Since I only have 2 arms, I can't manage to hold the camera, battery and test-rig at the same time. But pics will come! A guy I know has promised to come by with his 2009 Wilma, and I think I should be able to get hold of a L&M ARC to compare with also.

    I had to file off a little of the base to make room for all 8 solder-points(I removed the double-sided tape that sat underneath prior to taking the pic):

    I think that this filing is needed even if you have a 4s star and only 2 solder points.


    Test-setup:



    To sum it up:
    I think Ledil has laid a golden egg here



    As a side-note - this is the MC-E I recieved from DX:


    = sh!tty quality control (and soldering for that matter)!!

    I thought we all had to go through the typical BS of shipping half way around the world-only to ship it back.
    Seriously though, Ledil will process orders direct or is there a minimum order?

    Feck me what the hell have Ledil been playing at these things should have
    been on the shelves for when the MCE hit the shelves .

    they will have had samples for R&D way before then .

    so it will be december when I get mine

    I hope they live up to expectations .
    and all this time has been spent getting perfection.

    I just used sales[at]ledil[dot]com found here
    http://www.ledil.fi/index.php?page=contact

    I ordered 6(!) pcs for testing purposes. They were 0,89 Euro + 22% VAT a piece.Shipping from Finland to Norway was 15 Euros + 22% VAT. Quite steep shipping for 6 pcs in other words..
    My impression is that they would handle small orders, but if there suddenly comes in 100's of orders from DIY'ers things might change.
    But I guess if you US guys arrange a group buy, it'll be a whole different story.

    Beam-pattern:
    compared to a 3 x XR-E with 2 x 15 degree and 1 x 9 degree Ledil square lens @1A (my regular bar-light), the MC-E/Boom @1A blew the old light out of the water. Hotspot was a little brighter, but the spill was in another ballpark.

    This is a no-brainer.

    It's the BOOM-MC-S
    Product code: 10569

    ..and what you asked for: 10 degrees. But that does NOT include the spill!

    As you can see on page 2 here
    http://www.ledil.com/datasheets/DataSheet_Boom_mc.pdf
    the spill light is approx 35-40 degrees!

    US guys Digikey has the Ledil line listed as shipping on Dec 4th. I put in a small order of both the boomerang and LM1 just to see when I get mine.

    I'm thinking about putting in my order to Digikey for narrow and medium, any reason to even consider the wide?

    Polymer optics ?

    It seems that if the 6deg becomes a 10deg with the MC-E maybe the concentrator they make will be usable with the MC-E. The concentrator is a polymer optic for fiber optic light insertion with with the XR-E. Its a super narrow beam, like 3 or 4 deg. I may eventually try this out. This could be a nice narrow spot option for the MC-E.

    Still no sign of the EVA? wow ledil is slow.
    I guess the 5 up 35.5mm XP-E and the 10mm round single XP-E smooth spot wont be available until next year at this rate, and by then there will certainly be a new led available....

    Any one in the US have an extra boomerang SS reflector they want to sell me?
    Shipping from cutter or digikey is a lot since I really just need 1 boomerang to replace the lame LM1.

    LM1 from cutter not the right part #

    Just checked out the Ledil stock at digikey. The LM1 from digikey lists 4 parts. The data sheet shows photos of 4 optics but until now we couldn't get the frosted one shown in the data sheet. Digikey says the LM1 comes in 4 flavors, real spot, Diffuser, medium and rectangle. The diffuser is the 20deg part I got from cutter that is so disappointing. Digikey and the Ledil data sheet dont list a beam angle for the real spot. Guess I will have to get one and play around with it.

    wow all these people with MCEs and no good optics

    it would seem and this is from another party that Ledil did a production run of optics but they were not good so this is where the delay has come from redoing or even redisigning the optics .
    so this may be a good thing rather than them putting out a design that was bad.
    unfortunatly buying an optic when all we have seen is a white wall shot and some mumbo jumbo that only a few will understand is not ideal .

    maybe we should have been more aware about the problems these multi emitter devices have from the P7 .

    as you know I have tried a few options and have been a tad underwhelmed but have on order like some on here the ledil options I am not antisipating any great nirvana just hoping for something better than I have tried .

    I wonder what Polymer optics have come up with and are they on the shelves yet .

    Here we go!

    Then I've had myself a little walk outdoors.

    Note to self: It's hard to take decent pictures without a tripod/etc. Especially picture nr 2 is a tiny bit blutty.

    Lights used:
    - 1 x Cree MC-E + Ledil Boom reflector, 10 degrees @1A
    - 3 x Cree XR-E (not the latest bin) + 2 x 15 degrees og 1 x 9 degrees Ledil square [email protected] This is the light I've happily used as a bar-light for the last 2 seasons.

    In the backyard:
    3 x XR-E:



    MC-E:

    (Blurry - I know..)


    In a park nearby (pictures taken a little from the side)
    3 x XR-E - 2 pics where I held the light a bit different:






    MC-E:



    Especially the last picture shows how defined the beam is. IMO this is a good thing. I'm not sure whether the pics show the good combo of hotspot and huge spill, but it's there. Trust me.

    It must be taken into account that the MC-E light has 33% more light than the XR-E.

    All pics taken with F = 2,8, ISO = 200 @ 1 second.
    Since I used an Ixus with not-so-good wide angle, it was actually a bit hard to really show how wide the MC-E beam is.

    Conclusion: I'm sold!

    Next step: Build a housing for this sucka

    uk group buy from ledil direct?

    Is any one in the uk going to buy some Boom reflectors direct from ledil as i would be interested in buying 2 10 degrees ones?

    and has any one heard when cutters are going to get them?

    I can't say I see a hotspot, but hopefully there really is one! My 3x R2 bin with 1 wide (15), one smooth spot (7) and one real spot (6), is just spotty enough. Actually a pretty good balance between spill and spot, though more punch wouldn't hurt. I'm afraid the MCE may still not be good as a helmet light. Probably a great bar light though!

    Digikey should have the -RS version of the LM1 soon and despite the far less than good results from my LM1-D part I still want to try it. And the boomerang as well. Some time next week or maybe tomorrow i will finally get around to posting pics of my little MC-E helmet light and maybe some crappy beam shots too..
    There has to be some way other than a 40mm reflector to get a nice spot out of this thing...

    I can't wait to see the pics!
    I agree... there has got to be a way! ..and my design counts on it, so it has to happen!

    langen, use trees. Press the camera against a tree for a long exposure shot. The point of focus for both lights should be the same for a fair comparison. Just from the blurry shots alone, the Boomerang looks to be a fantastic option. I am a big fan of the square Ledils but this looks like an excellent replacement.

    Or sit it on top of a park bench or a fence or something sturdy. Set the automatic timer so that the camera is nice and still when the exposure happens. That way you don't wobble the camera when you press the button. Saves having to track down a tripod

    Is the DX MC-E supposed to be soldered so that you can wire them any way you want? As in each wire on the emitter is connected directly to the solder pads. I see that in the picture the solder on the 3 wires are touching.

    Are the MC-E's from cutter that are wired 2P2S just done with the spaghetti of red wires like I saw in the pic in this thread? Isn't there a way to do that within the pcb the emitter is attached to? The red wires seem like a mess...

    No, it's not. All 4 legs are supposed to be connected together, not just 3...

    When I ordered I specifically asked for a 4S setup, but I didn't think that the configuration would be done with wires. It shouldn't be THAT difficult to get hold of a 4S star-board??

    I know.. The pics does not do the Boom justice. Maybe I'll get time tomorrow night to take some better pics.

    UFO landing in the backyard!

    The lights are the same as before. They are about 3m from the bushes. Pics are F = 2,8 and 0,8 seconds.

    3 x XR-E:


    MC-E w/narrow Boom:


    Hopefully now you can see both the hotspot and the crazy spill.

    Convinced? I am

    Thanks for that Langen
    That is looking encouraging on the beam with the centre being nicely defined .
    and Cutters say they will be shipping back orders this week

    The hotspot is clearly more visible in the new pics. Nice work

    Looks like it is the leader for MCE optics at the present.

    Can you tell more about the setups? What mA is each running?

    Great shots, I'm very shocked how wide the MCE beam is even with the narrow optic.

    Same as with the first pics:

    Lights used:
    - 1 x Cree MC-E + Ledil Boom reflector, 10 degrees @1A
    - 3 x Cree XR-E (not the latest bin) + 2 x 15 degrees and 1 x 9 degrees Ledil square [email protected] This is the light I've happily used as a bar-light for the last 2 seasons.

    My apologies for being dense, the MC-E @ 1A, is this 250mA per facet or 1A per facet?

    Looking good!

    I'm still a bit skeptical that the BOOM will have enough of a spot in comparison to the spill. I might go from a triple R2 (CRS: 1x RS, 1x SS, 1x M) to a dual MCE (2x BOOM SS?) and I want more light in general, but I definitely would appreciate more spot/throw. I don't want to just flood the immediate area with light and then actually make it harder to see further ahead... This would be for a helmet light, mind you; I'm sure the BOOM reflectors would be absolutely awesome on the bars.

    I'd be interested to see what different combos could look like... a SS or M BOOM, and an asperical (unfocused) optic... Might still look funny as I suspect the aspherical would leave quite a defined "circle"/hotspot.

    I'm excited to see more beamshots and see how the other optics turn out! And comparisons like this one and others are always a huge help.

    1A through all 4 dies. Above the max rating in other words. It gets hot!

    In theory the Buckpuck will go out of regulation somewhere in the discharge curve, but I haven't come to this point yet.

    Btw - what happens when the Buckpuck or bFlex goes out of regulation due to too low battery voltage?

    I thought the light just dimmed.... but i might be wrong. I was planning a 700ma buckpuck with a 14.4v battery so i will probably face the same problem.

    From memory of Trouts MCE runtime test, his Low voltage protection kicked in before the light noticeably dimmed...

    Yes
    They go into "direct drive" which means they supply as much power as they can. You notice on the bflex because you lose the upper drive levels one at a time.

    This is not harmful for the battery or driver, right?

    Not in itself. In general batteries don't like to be fully discharged hence the battery voltage warnings on the bflex.

    and adding to the collection

    I had been reliably informed that the Cree XRE optic XLSL-7090 would sit nicely over an MC-E (apologise but I have forgotten who to credit for this but thanks).

    As they were about the perfect external diameter and overall height for what I was looking for I used them in my MCE build. The pics below are solely to illustrate the beam patterns and have been underexposed.

    MTBR XLSL Beam shots.jpg

    I am surprised at just how noticeable the "cross-hairs" are in the multi optic pic. I'll do a few trail tests and if it is noticeable I'll play with some very fine wet & dry paper to "frost" the lense and see how that goes.

    The 25* appears to have a significantly lower light output in the pics. In reality it is there but because of the underexposure the camera hasn't picked up the amount of spill.

    As a side note for anyone that cares to calculate beam angles, the light in all shots was set up 2m away from the wall and the width of the beam in the single 8* pic is 900mm from side to side.

    Oh yeah, the optics do sit down over the LED "dome" perfectly.

    900mm at 2m gives about 25.5 degrees angle.

    I could also clearly see the 4 dies in the Carclo (non-frosted) narrow 26,5mm lens. With the medium frosted, however, I could not make out the 4 dies from another.

    I think this is a limitation wrt narrow lenses for multi-die emitters. To get a really narrow beam, it seems like you need a clear optic, but then the individual dies are visible...

    I still think the Polymer Optics range holds great potential in a package only 15mm across.

    The beam shots on their website would indicate there is little to no evidence of donuts or cross hairs. This with a claimed efficiency of >85%

    PE 10degree.jpg

    Anyone out there tried one of these yet?

    I just got my Ledil Rocket 3 ss optic to replace the Kathod triple I trashed with solvent
    and have done a beam shot .
    it is certainly as good and does have a hot spot so I will not know untill it first ride .

    I changed the camera setting to 4 seconds @ f4 .

    Troutie... the triple rocket lens looks nice. Anxious to hear how the ride test goes.

    FYI... for those who have ordered, and have been waiting for, Boomerang reflectors from Cutter, I got an email from them today notifying me that my order with 2 MC-E (M-bin) and 2 Boomerang reflectors shipped today. Yeah!

    The test ride could be awhile as the weather is pretty rubbish at the moment .

    Could be a few boom pics soon as it seems they are shipping now I just had the same message from cutters .


    It Also seems like the EVA has had problems .


    It is odd we can split an atom but cant focus a multichip led .

    Has anyone tried any of these optic ranges yet?

    C'mon Troutie, its your local company can't you knock on the door and ask for some samples, show 'em some of your work, you're bound to get something.

    I have wanted to try there stuff and have emailed them about supply
    they gave me this co
    http://www.anglia.com/

    7 emails later with no reply
    and went through the process of opening an account
    still zilch.

    reported them to Polymer-optics and explained

    reply from them saying it was not good

    They then said try this co
    http://www.plusopto.co.uk/

    I have not yet tried them or had a good browse round their site


    I was hoping someone else would have done a build and reported on them .

    I wanted to put 6 into a maglight head
    with Georges HipFlex

    I have the mag head ready and anodised just waiting , waiting , waiting
    something I have now learnt to do .





    Maybe If I bought a full tray of the things then flog them as a group buy
    But would like to see a beam shot from one first

    Yeah I've got one 10deg. Its nice and smooth but too wide for my taste.

    The 30mm 5deg reflectors might be the business.

    Any chance you can set your light up 2m from a wall, take a pic of the beam and measure from side to side to give us an idea.

    Also do you have the MC-E version or the XP-E version or are they one and the same?

    This is the MC-E version wired like:

    To give a hotter spot at the top.

    Beam setup geometry is what Troutie came up with when he wasn't allowed out of the house.
    I forget exactly what it was.


    I'll probably do a dyno light with this to try out some standlight ideas.

    Wow I am all but sold on the XP-E and XR-E being superior to the MC-E for spot use. Too bad I already drank the cool aid and built a MC-E helmet light. Not totally bagging on the MC-E thought, a Mr16 triple MC-E on the bars ought to be unbeatable. That polymer optic looks to finally be one that does the job of making a true tight spot but its huge. The data sheet shows it needing a 37mm diameter with lots of filing. A 4 up XR-E mr11 is smaller. So is the new and as of yet unproduced Ledil xp-e penta mr-11. Seems like I should try the regular compact polymer optic as a replacement for my LM1, should be a little tighter at least.

    Check this one out

    This is an optic out of a cheap led torch I think it is a Q something but the power is not an issue .




    What it does highlight is the problem with optics for the MCE .

    Camera set to underexpose to show the beam 1/10 sec @ f8

    the ceiling is 2.2 mtres from the light in each shot
    the tape is 1 metre eachway .

    first shot is the torch which is a cracking throwing beam with not much spill.




    next is the same optic sat on an MCE @ low on a bflex.



    same on hi to show the spill too



    It just goes to show what a flood monster these multichip leds are .

    A glass cover?

    So I'm pretty sold on the BOOM-SS reflectors. And they are super cheap at digikey.com

    But, what should I use for a cover to keep dust etc out? Any body find a good source something high performance like treated glass? (to minimize back reflection)

    Any at digikey.com? ..or another 'non-cutter' source.

    Much appreciated, Thanks!!

    UCL lens. Cut it down and make a holder for it to cover the Boom.

    Nice ..mucho $ though. Thanks for the link!

    I actually realized I know a local plastics house that specializes in acrylic and other plastics. I'm pretty sure they would have an anti-reflective acrylic plastic there, and sell by the SQ foot. Can hole saw me a bunch of replacements too!

    UCL lens have a much higher transparency that typical acrylic, lexan, or other "clear" plastics. Yes expensive but worth it on a good DIY build.

    From the link:
    98% light transmission, with Anti-Reflective coating, this is the highest performance lens you can buy for your Mag® C and D size flashlight

    lol ...one of those, 'you get what you pay for' deals is it! Ya you're, probably right, but I'm super budget. Squeeking out the door at $50 for my MCE build, trying to keep it under $50 for my next DIY project post. Thanks

    Have you tried a welding cover plate? It is a clear lens that covers the dark, glass lense.

    Dx has some cheap glass lens, just flat glass and no coating. Fancy coated and even sapphire treated lens can be found here -
    http://theledguy.chainreactionweb.co...cPath=48_50_66
    My light is housed in a 22.2mm internal diameter part. I guess I could file/dremel out the end to fit the 22.5mm.

    Smile Early lndications are for a

    I think but it is a bit early yet to get excited .

    I thought before I put all three in the triple it would be good to get the ceiling shot for a comparison .

    2.2 metres to the cross which is 1 metre each way .

    Before you get all spendy and order booms this is the quad cute narrow optic and 4 Q5s
    as this seems to be the best spot out there.



    this one is the Rocket ss XRE optic on a MCE and if I could fit 3 in the mag head then this would be my choice






    This is the Boom spot on an MCE




    So based on these results I have taken the plunge and installed them in the triple .



    It is a bit messy with the blobs of silicon to hold them in place but I was at a loss for a way to fix them and this seemed ok

    I had to stop the camera down a fair bit for this shot but on the ceiling it is looking good
    hopefully it will be the same on the trail .




    trail shots will be to follow when the silicon has set

    Anyone thought of trying microscope cover slips as glass covers? Kind of thin, but perfect optical clarity and super cheap for a box of 50 or so...

    Is the boom corona as wide as it looks on the pictures?
    When looking at your beamshot I would estimate the spot to 55cm and the corona to 90cm.
    Does the numbers sound reasonable to you, from what it looks like in real world?

    Yes that seems fair though there is a larger corona or spill that goes out of the picture also .

    I just pointed the triple out the window and am very pleased with what I saw .
    It is the best yet and should be awesome on the trail .


    Question for the maths experts .

    I am running the 3 MCE at 600ma and they are speced at 700ma
    How much light does this equate to and would it be worth the effort of installing one of georges new HipFlexs when available

    spreadsheet on http://bikeled.org/

    there is a spread sheet on http://bikeled.org/ the link is in the paragraph below the picture of the mce and boom.
    or http://bikeled.org/MC-Ex2.xls

    that should help abit

    did you get boom's posted by airmail from cutters?

    It looks really smooth with lots of spill. The hotspot is about 14 degrees and the corona about 23 based on the above numbers. Spill looks huge. Probably because the reflector is so shallow.

    Going from 600 to 700 will be roughly equivalent to adding a XR-E R2 at 1A. I myself wouldn't pay the extra (expensive) $ for only this.

    You are of course right what is an extra 240 lumens when I have nearly 2000 already .
    then there is the heat and battery runtime .

    Just shining it around my house I am very happy with the results and cant wait to get out on a trail with it . It seems to have everything I wanted a nice punch down the middle with a good wide spill . I have noticed there is a lot of heat radiated out of the front it seems more than a solid optic .

    I think a lot of the spill is coming from light that is missing the reflector and there is a very definate edge to the spill


    At the moment it is a huge

    boom vs rocket

    I picked up a bunch of Rocket SS lenses hoping to use them for the MC-E...but not sure I dig the 4 leaf clover beam. In you pic, the boom reflector looks even, but less intense. Is it more of a flood?

    On the trail the clover leaf is not noticed and if you have it diamond it works well
    if you were using multple then you can cancel the clover leaf .
    there is not much spill from the rocket ss

    there is a fair amount of spill with the boom but it does seem to do a good job I was very sceptical it was going to deliver and am happy it has . it is probably the best for a 20mm optic .

    Hi Chris
    Check the intensity graph on the Cree datasheet, you will find 600ma is approx 1.55x the 350ma rating

    No, no, not those beam shots. We want trail beam shots

    And while you're at it can you pull up a collection of the next best optics and put them all side by side with the boom to make it easier for us to compare without having to scroll? (I did mine on photoshop, only took a couple of miuntes) C'mon Chris what else do you have to do, watch reality TV?

    Oops, sorry mate. I just realised the pics of Freddy Kreuger standing in the snow were the new boom reflectors.

    As for my trail shots, the better half is away again and someone's got to watch the little'ns.
    I'll try and do some video Thursday night, if not I'm afraid you'll have to wait till the new year, sorry

    I have had to register again as my old ID won't let me post.

    Thanks for the beam shots, I was waiting for the beam shots on this thread, didn't expect them in a different thread. I have been lurking around for a few years and following your projects on this forum and STW, letting you do the hard work. Have you considered making and selling a few of these triple mce lights? or is that only for riding buddies.

    Abailey.

    I do make a few light for others , I am on with 3 at the moment for folk off STW .
    and have a few housings scattered around the world.

    It is becoming not a viable option for cheap lights any more with the cheap torches coming out of China . and the whole money exchange rates being crap .

    So I thought I would not do the cheap ones as much and do a few really good ones to beat the expensive lupine stuff .

    If I do a few for the odd customer it funds the habit of continual improvement so keeps the CFO happy .

    I am doing a light at the moment for a customer and if it comes off will be quite something

    Also my old builds usually sell when I do a new one

    Have been testing a few reflectors in search for a tighter than the Boom SS.
    Only found one (DX sku14599) that gives a round and smooth beam, unfortunately it's 35mm. About 8 degrees hotspot and a 20 degrees corona. Same distances as Troutie's setup for easy comparability. (2.2m to wall and 1m between marks.)

    That is some good detective work. Something tells me that since the overall size of the light source is so large, the only way to focus it is a large reflector which isn't very compatible with compact builds.

    The beam pattern looks pretty darn good though!

    yes, but what's the use when the diameter is so large? I would rather use a 4X Cute instead. More bins and tints to choose between, possibility to drive them at 1000mA, better thermal management. But a reflector looks much nicer the a plastic lens

    Will post a list of all reflectors tested in a few days, so you can see what not to buy. (waiting for two more to be delivered)

    Great beam that one Shame it is 35 mm though.

    I have to aggree with your comments there too .

    Oh well we keep looking .

    There was an excelent link over on CPF explaining why it is so difficult for these multichip devices but I cant seem to find it again , it was by a Carclo boffin in a magazine.

    Yes, but it is more faint than it appear in the picture and very hard to see.
    A problem with the reflector is that it's made to have one of those screw in cups like the ones in the P60 modules, but comes without it. The cups in the P60s I had lying around didn't fit, so I just filed down the flange making the bottom of the reflector flat.

    Just noticed I already had bookmarked the excellent article about multi versus single die emitters Troutie was referring to. It can be found in Electronics Weekly.

    Here comes the reflectors not to use:




    1.Kai smp cree reflector sku S005040
    2.Kai smp cree reflector sku S005039
    3.Carclo 80 degree reflector (beam is much wider than picture)
    4.Fraen 7 degree cree reflector
    5.Kai 26mm OP reflector sku S005406
    6.Carclo 10209 MC-E 20mm medium ripple lens
    7.Carclo 10195 MC-E 20mm medium smooth lens
    8.Kai Wide SSC 35mm lens sku S005131 (beam is much wider than picture)
    9.DX Spot cree 35mm lens sku 04544
    10Prolight 10 degree reflector Besthongkong

    The Fraen looks quite good but is not. It sits too high on the led, blocking lots of lights. Hotspot has the same brightness as the 26mm OP reflector, which gave the best and brightest beam. Not good, but best of the 10.

    I also tested another one, but forgot it when I put them together. It is quite good, but have a weak doughnut and cross in the middle.
    Kai 23mm cree 10 degree lens sku S004594



    I'll probably go for a BOOM SS for spot, but I'm also looking for very wide optics that gives a uniform brightness all over the beam. (no hotspot) Preferably 60-80 degrees. Field of vision is about 80 degrees... Carclo 80 reflector works great with a SSC P4, but I have no space for 3-4 reflectors + the spot reflector(s).

    whats wrong with 4,5,7?

    4 looks nice and tight, a bit mis-centered.
    5. looks smooth
    and 7 looks like a nice flood.

    Yes, I may be a little picky... nr 7 is a very good 25 degrees except is square, not round.
    nr 4 is a little miscentered as you say, I dind't notice untli I looked at the picture. But.. the Fraen (nr 4 ) looks quite good but is not. It sits too high on the led, blocking lots of lights. Hotspot has the same brightness as the much wider 26mm OP reflector (nr 5), which also gave the best and brightest beam. Not good, but best of the 10. It has a dark spot in the middle.

    Great work there and thanks for doing it Gillestugen

    No 5 looks ok for a spot but then it is a larger reflector and no good for my builds

    So it looks like the Boom SS is the favorite on the small ones to use list.

    It is like the search for the holy grail.

    how are you guys testing all the lenses?
    i've got my test led setup, but with all the different lens sizes, i can only shoot straight up, since nothing is really holding the lenses on.

    Looking at the ceiling, I gotta say, I wouldn't really mind any of the optics I've tried.

    The smoothest thing has actually just been putting a tube over the led, not as bright, but smooth.

    I do kinda like the cheap reflector that came with a DX 3W cree LED flashlight. Smoother than the 20mm carclos I have, but still decent throw.

    The ceiling is great that was my method I put a cross of tape 1 mtre across
    and it was 2.2 mtres from light to ceiling.

    And I think Gillestugen did the same measurements for his excelent optic test.

    Guess I should post a link to my pics as well. As well as taking the picture I use a lux meter to measure the maximum lux at 1M. This realy should indicate what the potential throw is as well as the picture indicating somthing of the spread. I am not very happy with anything I have seen yet. Just ordered some of the mce specific square lenses and EVA's from Brams group-buy so will be testing those as well. hoping for more thow from the EVA's

    Awesome! So is it just me, or for the hot spot, are the LM1 and the Rocket SS both better than the boomerang? The spill around the hot spot isn't as nice with those, but perhaps with the two combined, or with one of those and a Boomerang, it would smooth out...

    Thanks for posting that!

    Thanks a lot for the great beamshots! The manufacturers always crop and resize the pictures so the hotspot fills up the image, making it harder to compare them. Your pictures really makes it easy to compare them.

    In terms of max lux eg throw capability the narrow LM1 is better than the narrow boomerang with a max of 3350 as opposed to 2410 and the xr-e designed rocket are square RS are both better at 4460 and 4660. I just found the numbers for the rocket and RS with a Q5 xre and they both came in at 2500 when I was testing originaly hence my disapointment with the mc-e numbers.... We will see once I get the designed for mc-e square optic and the eva...

    The max lux is of course only half of the story I would hope that the MCE designed optics are producing more lumens eg total light we now you get a good flood light with them but measuring that is behond me.

    Ledil Eva and others beams

    I just received a parcel from that nice man Bram in the netherlands with some optics to play around with .


    So first up lets get some ceiling shots to see how they perform.
    these are well underexposed so brightness will have to wait for Ifor to measure when his arrive.

    first up is the EVA Wide


    EVA-medium


    EVA-difuse


    EVA-medium - modified by trout


    TESCO torch optic


    CMC-difuse


    CMC- smooth spot


    CMC- real spot


    LM1- real spot

    Troutie. What did you do to modify the one you labeled "EVA-medium - modified by trout"? Also, did you not get an EVA SS?

    Great new set of pics trout! Thanks for ordering one of everything so that I don't have to

    The EVA diffuse, CMC real spot and LM1 real spot all look nice and tight. Especially when compared to your Boom pics on page 6. What does it look like to the naked eye.. Is there a winner? It looks like the MCE is finally showing some of its potential.

    Well for biking the wide is a write off mega waste of lumens .
    the medium is what I would call a flood and is nice for all round the front of the bike but on its own would be limiting even I could outrun the beam .

    The difuse I think is the SS and is not too bad on the ceiling shots cant try on the trail as no host yet I may cobble something up after xmas day .

    What I did do with a medium as I dont think it would have ever got into one of my lights
    was sand it flat on the front it lost the bobbles and the concave front and it seemed to tighten the beam quite a bit I will do some pics to show exactly what i did.
    this did not inprove a SS when i did it it just showed more clover leaf .

    I dont think I will do any EVA lights though might try a single for helmet use .

    the square CMC SS and RS look to be the best along with the LM1 RS

    I have some Polymer stuff on its way for Stevemorgs build so will get an idea on their beams hopefully before the new year . they were dispatched mon from Cutters

    Some of the XRE optics will work with the MCE but not too well .
    If you hunt through my threads there are beamshots from any I tried.

    the best I found was the Rocket SS
    and The square ledil SS and RS

    If I use EVA-D and EVA-M in a helmet light, and no bar light at all, would that work as an all-around MTB bike light?

    From my findings I would just use 2 EVA-D and forget the M unless you want lots of flood lighting.

    Ledil Beamshots

    Ok I had a bit of time to get out and do some trail shots for the ledil optics I recieved before xmas.

    Here is the setup we have some torches in Tesco s which have a bit of a following over here . and this is its bigger brother the C cell model which is a superb host for the EVA optics and also a 35 mm cutter quad kit is a good fit with minium work or tools .

    Hey Troutie- The video was great. It gave a good comparison of all of the optics as it rolled through. Do you have more information on the Tesco light? I don't recall seeing anything on the build. I like the idea of being able to change lenses like that for comparison.

    Thanks!

    this is the torch in question whole and dismantled



    it is only available in Tesco stores for £10/£12

    No details yet of the build as I knocked it up quickly to get the Ledil beamshots.
    and probably the easiest build I have ever done.
    I will do a rundown of the build later .

    Thanks a lot. Chasing down the light in the states might be tough. It looks like it would make a quick road light.

    Extra Beam Shot Added

    I have added the Ledil LM1-RS to this collection of shots
    I think it has a pretty good beam too,

    All these shots were taken @ f6.3 and 5 seconds white balance - daylight.

    If you have any other MCE optic beam shots send them to me please and I can put them in for a comparison .
