    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.

    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

    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
    Peter

    PS: I'm looking at building a new light set for my 46 mile round trip commute(!)

    Code:
    Vf	mA	W	W (x4)	% lm	lm	lm/W	x3 (W)	lm	Run time
    3.20	0.35	1.12	4.48	1.00	456.00	101.79	13.44	1368.00	5.28
    3.10	0.20	0.62	2.48	0.60	273.60	110.32	7.44	820.80	9.54
    3.30	0.50	1.65	6.60	1.35	615.60	93.27	19.80	1846.80	3.59
    3.50	0.70	2.45	9.80	1.73	788.88	80.50	29.40	2366.64	2.41
    (A 20W set fire to the tarmac temp boost button might also be called for!)

    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.

    Yet another Cutter R2 Triple triple DIY light...

    Cheers
    Peter

    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?

    Cheers

    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.

    Cheers salty
    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
