    That's how it came. It came in a bag in a box with the rest of the stuff. The bag has a hole in it, and the box is scuffed up. Everything else seems fine, though. I've wired it back together. We'll see how long it holds up.

    Thx for the quick feedback! Damn, really hope you can fix the light. I 'm looking forward to my "modular"...

    I am also thinking of ordering another light to compare it with Solarstorm X2. Does anyone have light mentioned in this topic and X2 and can compare them?

    Also this one looks interesting:
    http://www.kaidomain.com/product/details.S022462
    Anyone tried it yet?

    I would like to try XML2 light, but there is not too many to chose from (suitable for helmet use). Is difference between xml u2 and xml2 noticable?

    I have both, but I've yet to go on a ride with them. The 880 clone has a smoother progression from its hot spot to the edges, but that's expected from an OP reflector. The smooth reflectors on the SS X2 are a weak point. There are hitches and gaps in the beam pattern.

    At 100% they're really pretty comparable in brightness - plenty bright for any trail riding I'll be doing. There's a big gap between mid and high with the SS X2 and a big gap between low and mid with the 880 clone. I do like the UI of the 880 clone much more. One switch for power, one to toggle between modes. The X2 goes dark after high, with its one button.

    I'll write up some more after I go for my first ride, though that probably won't be until next week. Damn that whole 'having to earn my paycheck' thing!

    Ridiculous!

    How's the beam shape on this thing?

    I'm looking forward to your review.

    Does anyone have a photo of the clone next to a real MJ-880?
    I just saw my first MJ-880 in person last week and was impressed by how small it was.
    But the clone isn't the exact same, so I'm curious how it compares in overall size.

    I can take measurents when I get home, but the unit is definitely small. I can't imagine it being much smaller for a 2x unit. Additionally, I believe the lighthead unit itself weighs 135 grams.

    K/D 2 x XML, MJ880 Clone

    I've had a couple of night rides on my SSX2 and this 880 clone, now, and I have to say that I'm pretty happy with the combination.

    The 880 clone has a smooth beam patten with a gradual transition from spot to flood. Perfect for running on the bars. Low mode was great for climbing, and high was super bright, giving me no pause for speed on a couple of descents I'm fairly familiar with, though have only ridden a few times at night. The UI is great - one button for on/off, and another for low/mid/high (hold for strobe). Really, really like it, except for it being delivered with a severed cord. On my latest (longer) ride, I went for a two hour ride at dusk, ran it on low for an hour, and high for a half hour and never had it change from green.

    The SSX2 was good, but not great. Their low and high intensities were pretty similar, but the mid on the 880 clone was much, much brighter than the SSX2. Often, I ran the X2 on mid while I had the 880 clone on low. Side by side, the X2 beam was brighter, but since the X2 was on my helmet, I had to have it brighter for it to not be overpowered by my bar light. On full bright, the X2 was great in the short to mid range, but diffused too much beyond 20 feet or so.

    The other issue I had with the SSX2 is the beam pattern. My smooth reflector has a little lip in the middle (a defect), which causes a slightly darker spot in the middle of the hot spot. I'll bet it'd be just fine if it didn't have that problem.

    In short, this is a pretty good setup for the kind of riding I'll be doing. I might be on the lookout for a helmet mount with better throw, though.

    Interesting. I'm planning on using the 2x on my helmet with a 3x on my bars. On my short rides so far with both mounted on the bar (3x aimed downward, 2x aimed straight out), I was very pleased with the throw of the 2x. Add to that, since a helmet light has to be versatile to see both long distance and near distance (such as navigating through turns), this light seems ideal. I guess I won't know exactly how ideal it is though until I actually mount it to the helmet.

    You should add this to your previous post. Also, for reference, when I use '2x' here I am referring to the K/D 880 clone. I've never used a SSX2, but I am very much interested in how the 2x compares to the SSX2 and other similar lights. I just didn't want to confuse other people who might be reading this, or myself

    I just order one on KD too. Coud you give me please the diameter of the lense from the Kaidomain Xml U2 light ?

    On Actions led the wide angle lens is out of stock. I want buy one on another site.

    Thanks

    Let's make a small refresh of this thread. My light just came yesterday from KD, seems to have the same driver, LEDs on white circles, XM-Ls

    Perhaps responding too late. The lens is 20 mm, the reflector seems to be 20 x 14 mm, but Kir measured 21 x 14 mm

    Kragu, so did you try this lens? Maybe I will replace the lens too for some TIR lens like this or this

    Its a current on leds, its regulated to stay the same regardless of the input/battery voltage.

    Hi!

    This is my first post but I've been following this part of the forum for quite a while.

    Sorry if this isn't quite the right palce to post this, but here it goes:

    I've been using a single XML light (magicshine 808 clone) on the bars for about a year and i'm looking to add another light to my set up.

    I'm thinking on moving the single XML to my helmet and getting a dual XML for my bars.

    I've read this entire thread plus the one on the solarstorm X2 and the one on the gemini duo clones (yes i'm looking for a cheap light), and I'm not shure wich is the best option for a bar light, so help is much apreciated!

    I'm leaning towards the mj 880 clone. The beam seems to be not as focused as on the X2, bulding quality and heat dissipation seems to be better than average and I specialy like the UI (no need to go trough flashing and off while changing modes).

    Oh, and I like the possibility of replacing the cells in the batery holder with better ones when they die.

    Seems this clone doesn't raise the same interest as the X2 or the gemini clones (judging from the number posts in this tread) but i does look like a better option in my opinion, I'm i wrong?

    I also like the beam patern of the gemini clone, but the fact that I have to cycle trough off while changing modes, puts me off.

    I realise there are different versions of the mj-880s with diferent power outputs.
    Like this one with 1.8A circuitry and 580 lm (could that be right?)

    LetterFire LF-20 2 x Cree XM-L T6 580lm 4-Mode White Bicycle Headlamp - Black (4 x 18650) - Free Shipping - DealExtreme

    I'm thinking about this one, as it comes (supposedly) with XM-L2 emiters:

    http://www.kaidomain.com/product/Details.S021521

    Is Kaidomain a reliable seller?

    With the current li-ion batteries/air mail situation, i'm i likely to get it delivered with no problems?

    Also, i understand Kir got his clone from this seller and he measured decent current draw (I know that doesn't mean much and this is light roulete)

    Thank's in advance

    1. Yes, KD seems to be quite reliable I got the same light as Kir after a long time.
    2. No, MJ-880 clone is an XM-L U2 - confusing description.
    3. I have 2 SS X2 from lightmalls and 2 880 clones from KD. Both draw nearly the same from battery. SS X2 is a good helmet light and the 880 clone with TIR optics is a good bar light. I recently ordered 15 degree TIR lenses to replace one lense in each of the 880 clone and I might buy another two wider lenses to give outer leds wider beam. The battery pack from KD arrives by surface/ground post. THe light and stuff you get by airmail.

    I am considering this headunit only http://www.kaidomain.com/product/details.S022641
    I am also confused about XML2 description. It clearly says KD 2 x Cree XM-L2 U2
    So if emitters are XML 2*U2 then I expect 2 light units as it says 2xCree bla bla bla. I see the pictures there are old XMLs but still...
    Whats up with that?

    The one I bought a few months ago was XML U2, but it was stated as such in the description. It didn't say XM-L2 at the time. I would say that they must have recently upgraded the LED to XM-L2.

    The description of XM-L2 U2 is written the same as for the 3x unit they sell. I sent them an email when I ordered my 3x XM-L2 U2 light and they confirmed over email that it was an XM-L2. It arrived and was indeed an XM-L2.

    Honestly I don't know, maybe they changed emitters for XM-L2 and didn't updated the pictures. But I have 2 x 880 clones and both are XM-L U2.

    You are going to find that most of the Chinese light vendors are using the same stock photos....so the green LED may--or may not..be what's inside what you're getting.

    K/D updated photos to the new XML2 880clone headlight.
    Moving on...did anyone try to mod this light? Increasing current by replacing SMD resistor? Which resistor would be best to use? There is a lot of aluminum to heatsink for overdrive. You could machine new inserts (copper maybe) and adjust the dimensions to install plastic lenses and ditch the reflectors. (15° + 25° combo). Which lens are the best to fit?
    I have plan to do all that, but it would be nice to have some infos before I get my ordered lamp in my hands.
    Thanks

    Despite owning this light for several months (XML U2 version), today was the first time I did a real night ride and one with the 2x mounted to my helmet. I was very pleased with the performance. It was a little bit of an adjustment, since, when paired with my 3x unit on the bars, I had to aim the 2x higher than I did when I used two Lumina 650's. It greatly increased the range of my helmet light and it more or less blends in with the light from the 3x to give me a continuous and expanded visual field. Consequently, I feel that I was able to ride a little faster than last year's night rides. I ended up running it on HIGH for almost the entirety of the ride. When I put both it and my 3x unit on medium, the 2x unit just seemed a little weak. The battery power is there for me to ride on HIGH for 2 hrs and my ride was 1:30 so it's really no problem to leave it on HIGH the whole time. Very pleased with the performance, but I'd be lying if I didn't say I am envious of those newer XM-L2-U2 versions

    K/D 2 x XML, MJ880 Clone

    I just ordered two of the xm-l2 lightheads from KD. Along with some different optics from fasttech. Hopefully the optics fit. I plan to run both in the bars to create a nice flood of light.

    This will replace my current setup of a 4x XML and a v1 gloworm X2.

    I am hoping for a better beam pattern than the 4x provides.

    Same here ;-) Also bought 15 degree optics from fastech. We'll see how that magic performs. If they fit, I'll buy also wider angle.

    I picked up the 15 and 30. At 86 cents each. What the heck, why not.

    Can someone verify whether this has a standard Magicshine-type connector? The XM-L2 head-only is less than 30 bones on KD.

    Yes KD clone has MS type connector, however the cable is only 100mm long. You might need extension cable just to place your battery pack where ever you want to.

    Mj880clone does not have exact MS connector, but the headunit fits MS batteries (loose fit and not waterproof), however clone battery doesnt fit classic Magicshine light unit. The problem is the outside diameter that is smaller at 880 clone. Note that original MJ880 has different connector than other MS (it is not round)

    I want to mount a 880 clone to my helmet. Looks like it comes standard with bar mount. Is there a helmet adapter available to fit this head? I could mount it 'as is' but it would not have a way to swivel for beam angle.

    Cool-blue Rhythm

    Finaly...I got a new version KD XML2 880 clone. Head unit only.
    http://www.kaidomain.com/Product/Details.S022641
    Got some good and some bad news.

    Let me start with good ones.
    -it has indeed XML2 leds
    -it has standard Magicshine connector (picture on KD site shows connector from old XML series)
    -you get two mounting silicone o-rings and both are small size, so you get a good tension on a handlebar.
    -very fast delivery. Less than 3 weeks.



    and the bad news
    -very poorly packed. Only bubble wrap and standard chinese envelope. But it survived the journey.
    -very poor heat transfer design (SSX2 alike). It has slightly different design compare to first version with XMLs.

    You can see heat transfer contact area on a picture above. It is only that middle area with some thermal paste on it and some
    random contact points at the edges. The main middle wall is thicker compare to old one and if there werent those

    I think that this light is not very good as it is...it is not plug&play, but if you upgrade it, it could be very good.
    Driver looks the same.

    Tomorrow I will be able to compare brightness between this one and the first XML version.

    MJ880 clone

    I bought one in black from Kaidomain (XML U2 version with slim type connection). For the money it's good. Beam pattern is large bright spot and then a large spread. Very good for commuting. Have not taken it apart yet. I like the stealth look

    It is hard to believe that the same SS X2 thing happend to this 880 clone. I can see some thermal paste in the middle of the MCPCB. So both "reputable" kaidomain and fasttech are selling some weird clones of clones

    I have one heading my way. I'm a bit disapointed that the internals don't have the same design and heat transfer capabilities as the model Kir described.

    I also have the 15 and 30 degree lenses coming from fasttech, do you have any idea if they will fit this slightly diferrent design?

    (lenses are 20mm x 13mm)

    bhocewar bought light head only, Kir and I, we both bought the full set and have the same design and just XM-L not XM-L2. My 15deg. lenses stuck somewhere due to lifepo cells in the package so I don't know if they fit, but there is still alternative to buy from DX.

    No lens would fit as it is. You need to machine new inserts to elevate leds to correct position. That way you upgrade heat transfer too. I also hope that lens will hold OK. Front panel has 19mm holes, lens OD is 20mm, that gives just half mm at the edges to hold on a rubber gasket. You should avoid those 21mm lenses with plastic shell because it would not be waterproof (or just throw away that shell).

    Yesterday I compared 880 xml clone and new XML2 version, and I didnt notice any difference in brightness. Did not find spare time to measure the current draw.

    Here is a funny fact:
    880 clone reflector fits perfectly in SSX2. IF you want to have smoother transition from spot to flood...I will soon have extra OP 880 clone reflectors available.

    How deep is actually the reflector? I think I measured about 14 mm.

    All things considered, the 880 clone still looks to have more thermal contact area ( on the emitter board ) than the SSX2 clones not to mention it has a larger head for added heat dissipation area. Plus, the 880 clone looks ( as you stated ) like you could add extra pieces into the slots but likely you might have to go to a machine shop to get them made. Unless you can make the inserts yourself I'm not sure it would be worth spending the extra money. ( of course that would depend on what they charge you for something like this. )

    I thought that a mix of some copper shavings and thermal paste would might be worth to try, at least you don't need to pay for a precise manufacturing of those pieces. But that is just my suggestion ...

    Dont be cheap. Those inserts will cost a few bucks...and will improve heat transfer by at least 500%. I will overhaull my light to the point, it will match the original MJ880.

    To be fair the light head is only $29. So how much more of an investment are we looking at here? If it dies you can just grab another cheapo light head. Also it looks like the heatsinking is not as good but how much of an issue Is it really? Is there a good way to measure that?

    I did see some people on the blf forums make a heat sink from thick copper wire and solder. Then put it in with a bunch of thermal paste. That may be a budget option

    About $15 in material/not including labour/including a few other tricks.
    Thermal managment is the most important thing in light design and its performance.

    Got some good and some bad news.

    Let me start with good ones.
    -it has indeed XML2 leds
    -it has standard Magicshine connector (picture on KD site shows connector from old XML series)
    -you get two mounting silicone o-rings and both are small size, so you get a good tension on a handlebar.
    -very fast delivery. Less than 3 weeks.



    and the bad news
    -very poorly packed. Only bubble wrap and standard chinese envelope. But it survived the journey.
    -very poor heat transfer design (SSX2 alike). It has slightly different design compare to first version with XMLs.


    Does not have leds on stars and inserts but leds are on a custom one piece backplate that fits very loosely.
    You can see heat transfer contact area on a picture above. It is only that middle area with some thermal paste on it and some
    random contact points at the edges. The main middle wall is thicker compare to old one and if there werent those

    Well my two light heads showed up. Same issue. What size inserts are you making? It would save me from trying to shove some calipers in there!

    Thanks!

    I am making inserts to mod it with TIR optic lenses, so it is a different size. You need just to fill those holes... 18mm dia and cca 4mm thickness.

    Eventually you can make them thicker to heatsink the driver also.

    ...or you heat it up...
    I will use regular 20mm TIR optics (21mm with plastic housing) 10°+25° maybe 2x25° for handlebar

    more... when it`s done.

    It depends on whether the driver needs cooling or not.

    I was thinking about 15° and 30° for a handlebar. But now I am using 7 XM-L as a bar light and 880 clone will move to a helmet light so I probably won't change anything.

    My fasttech optics showed up today. Loose fit. Needs to be raised a mm or 2. I fit them anyway with 15/30 combo just to see how it looks. Beam pattern loses the hot spot. Def more flood. But for now I'll run stock until i feel like messing with it. Comparing against my friends yinding light. That thing is 1/2 the size and same amount of light. With a better beam pattern.

    Nice work! Inspired me to make a piece for mine so i can use my optics. 15° and 30°.

    Much better beam pattern. I am currently running both of my light heads on the bars. I'll do a ride with the modified optics and the stock reflectors to see how I like the difference.

    I have the Kaidomain version. Never opened it or addressed the heat dissipation problem - is that something I should do or it'll die on me?

    With regards to the beam pattern, I simply cut out a cheap plastic lens (intended to mod some common U2 lamp of larger size) and siliconed it on to one half, like this:



    I tried spreading the light from both LEDs but for me this strikes a good balance. Easy, cheap and ugly. But this lamp would still blind people and oncoming traffic so I also added a cap, cut out from a schampoo bottle.

    Unfortunately, the cable is complete junk and as you can see the cover is broken already (same goes for the battery pack cable on the other end):



    In your minds, what's the easiest way to repair that? Heat shrink tubing would require disassembly - maybe one could just as well switch it out to a new cable all together? I dunno. Just put something glueish on it maybe and see if it sticks?

    Anyways, the performance is good. It hangs upside down like this:

    That has to be the largest lamp hood I have ever seen. With the lamp being mounted as low as it is IMO I would think you could get by with just about a quarter of that. Not to mention that having the entire top of the lamp covered in plastic is going hamper the lamps ability to dissipate heat.

    Interesting mounting solution. I like it but my guess is that it would have to vibrate/sway quite a bit being so elongated as it is.

    Well I tried with a smaller hood first and it didn't provide a sharp enough cut-off for the beam. I want the brightest centre directed as far ahead as possible without deer-ing oncomers to the headlight. And in fact, the lower the lamp hangs, the more precise you have to be.

    The lamp never even feels luke warm when I touch it so I stopped worrying about the hampered dissipation. Maybe come summer I have to cut the cover narrower; it's strenghtened with construction glue anyways.

    The low mounting serves a purpose: otherwise my handlebar bag would block the light. Also, (especially since I sometimes use a head-lamp) the lower position makes for good road perception. The Topeak BarXtender does its job and I haven't noticed any vibrations or swaying at all. As a bonus I can strap the lamp on in two seconds because I never have to take the rubber mount off, instead just twitching it over the end of the bar.

    The battery pack normally goes in the bag. I hate fiddling with that flimsy mounting strap - and speaking of ugly I use a random piece of foam in between the battery and the frame when riding without the bag. With the wire all over the place, straps, pices of foam, a schampoo bottle cap and some random rubber band here and there it has white trash written all over it. Butt ugly would sum it up.

    Well it works for you and that is the important thing. You must have a heck of a time trying to reach the mode buttons when riding though.

    Have you ever considered a small frame bag? I use a small bag on my road set-up that fits nicely between the top/head and down tube. The advantage of this kind of arrangement is that it helps free up space around the bars ( vs. a handlebar bag ) and I don't need to use a bag under the seat. It's small enough that is doesn't interfere with the water bottle too. I figure with the lamp mounted on the bars you could more easily *adjust the lamp for on-coming traffic. ( * either by tilting the lamp down or changing modes )

    Anyway, if you are really concerned about cut-off for the lamp you might consider a dynamo light head. Most of the good ones are designed with cut-off in mind. Matter of fact I've been thinking of going dynamo myself for my on the road set-up but just don't have the money needed to get what I want. I don't worry too much about it though as I have good battery powered lights.

    After some time using this light with a couple of other blokes around I found out that the R100 resistor likes to blow up increasing its resistance from 0.1Ohm to xyzOhms. The light seems good overall, buttons all green but it won't power on - actually it does, but the amount of current is very low rendering the leds powered off. Changing the resistor and maybe a increasing its heat dissipation makes the light work fine again. That happens more frequently on the "solarstromified" versions of the 880 clone.

    I am new to LEDs, so can you explain the 10 and 25 degree optics? Is the 10 degree the original "spot", and the 25 degree is a swapped in "flood"? If so where did you get the flood?

    My source is local shop with electronic stuff, or you can go with Fasttech, DX, ...

    Here is the guide which SMD package will fit: Resistor Sizes and Packages » Resistor Guide

    The lager the resistor the more heat it can dissipate.

    Both TIR optics are added for an upgrade. Original light has OP reflectors

    Can someone tell me if the 880 clone has more throw than the SSX2? Also how does it compare to the SSX2 over all?

    The reflectors have similar dimensions, 880 is OP whereas X2 is smooth. 880 should push more current to the leds. I think the throw difference is negligible. Here is my photobucket album with some lights beamshots including 880 clone and X2. The quiestion is what driver X2 uses, 880 clone uses just one type.

    The triangular head (that fits the new Neutral White KD880 clone) might be more common outside the USA. It was not included in any of the multi-tools I've purchased previously and haven't seen it at my local big box store recently either. But then, NYC is no longer world-renowned for hardware. Could anyone here please provide a link or other reference so I can at least narrow down my search? Afraid if I just use the end of my triangular file it will abraid the finish of the screwhead.

    Also, if I find I don't have to (or can't) mod the innards with thermal slugs, what options exist to otherwise compensate for the shortfall with replacement optics?

    Thanks!

    Thanks Archie. From Wikipedia:

    Sizes include TA14, TA18, TA20, TA23, and TA27.

    By any chance do you know which size the 880 clone uses? If I could find the right one locally it would save the wait from China/Hong Kong/Australia or the expense of buying the entire set from Amazon.

    Unfortunately, I don't know exact size, but you may use ledoman's trick or similar method probably.

    Offtopic: are you sure it's impossible to find such tools locally?

    Well like I said, my triangle file is very rough on the end, afraid it would damage the screw insets. Local hardware stores don't carry a full set of triangle drivers, they sometimes include a single one inside a set of other drivers and hex wrenches but there'd only be a one-in-five chance it would be the size I need. Amazon does offer the full set, am currently trying to fill my cart with enough other items to qualify for free shipping. Any recommendations for soldering kit and precision tips? Gotta go check out the DIY forum!

    Still don't know about replacing the reflectors with the optics mentioned here, guesss if I get the light head apart I'll simply have to measure. Doesn't even matter to me so much how wide or narrow an angle; I just don't care for the current set up, hot spot is too distinct. Wonder why the clones all have OP reflectors rather than the optics of the original, could it have saved the manufactures on material or labor?

    Thanks Garry! Yeah I saw some, problem is the replacement precision tips are not sold in multiples, only variety packs seem to be available.

    Well as long as I had to wait for the optics from FastTech to arrive, ordered the complete set of triangular head drivers that -Archie- found for me on Amazon. Worked great, and a good thing too because I had to take that little sucker apart a good many times trying to figure out the easiest way to mod it without a workshop. Ultimately fashioned my own ~1mm thick plate to backup the emitter board using tinned sheet steel cut from the lid of a can of sweetened condensed milk and wrapped in aluminum tape, trimmed to size. Pressed into place, stuffed same NW XM-L2 3C emitter board with its two wires back inside. Dropped in the new 15º optics, retaining original flat glass lenses to both help fill gap and keep the narrower new units from falling through the front plate. Everything fits nice and snug, no rattling. Didn't break anything this time, finished it all without having to resolder the leads either. New setup seems to be working pretty well, shell heats up real fast — woohoo.

    Beam is still very tight, but without all the horrible ringing/color separation the previous reflectors had been putting out (will post some shots once it's dark enough.) Modded lamp will live on the bars as my "Driving Light." When the elliptical lenses on order from LEDDNA come in, will insert those into some other lamp for use as a low beam.

    Thanks guys for all the previous examples. Now let's just see how long this one lasts.

    Looking at your photo I would of thought the original reflectors would of been OP or faceted. I believe the original 880's used faceted reflectors which would of provided a more smoother beam pattern.

    Yeah Cat, the KD MJ-880 clone did come with OP reflectors, don't think they are the same or even similar to what MagicShine uses though, from what little I could glean from the pics on their site. KD's blur the distinction between spot and spill but somehow separate out the neutral white tint into alternating rings of sickly yellow and blue. Think that might have been what tigris99 was experiencing with his SS X3 too before he modded it with optics from LEDDNA, had said the NW XM-L2 emitters were putting out too much yellow before but that now they all look fine.

    I've still got an unaltered NW KD here I can compare beams shots to once it's dark enough. Not sure how well my iPad can pick out the rings though, auto WB kinda unpredictable.

    Incidentally, here's a slightly better shot of how the lenses from FT fit over the emitters, a lot different from the way TIR optics look.

    FYI, Original Magicshine MJ-880 uses 15deg TIR optics of same dimensions as LED-DNA optics. They are easily exchangable. It has been 10 days since I've put one 25deg instead of stock one. The light was used for caving so bit wider beam was desired.

    @andy, KD 880 is quite good regarding heating issues. I've used Noctigons and additional cilindrical inserts along with LED-DNA optics. Heat dissipation is so good I could raise the current for about 30% with no problems. With those mods it can easily compete with original MJ-880.

    Yes ledoman, this clone certainly has great potential. Think KD might even still be selling the original model with the heftier internals, if they've left that XM-L T6 model unchanged (the package price is still higher than the XM-L2, maybe for a reason?) Anyway I was pleasantly surprised to find that even my cheapy insert plate mod, which I performed really just to compensate for the shorter optics, has actually improved thermal dissipation as well: the lamp shell becomes too hot to hold almost a full minute before my unaltered Silver model does.

    iPad doesn't pick up exactly what the eye detects, but here are before and after shots of KD 880 clone with original reflectors top and modded with FastTech 15º lenses below.

    For under $2.00 in material, am satisfied with the results. And now I've crammed in the extra back plate, will be a cinch in the future just to drop in any other lenses might strike my fancy.

    Hey Andy you know u can get optics from led supply and mouser here in the states for about the same price???

    Just put these top of my next head to order (yinding on the way atm).

    Now something about beefy vs crappy internals???? Whats up there exactly.

    tigris, at the time I placed my orders, couldn't find the exact same lenses any place else. Not a big deal, didn't mind waiting as biking season is not exactly in full swing yet.

    Yeah if you read all the way back here on the KD MJ-880 clone, you'll see that they changed the internal design at some point. First model on offer was XM-L T6, it had either two separate emitter stars and a full divider wall or heavy pills, forget which. Current XM-L2 U2 version has huge circular cutouts and single emitter board, much like your SolarStorm X3. Dunno whether the XM-L T6 that KD still sells in a package is unaltered from that first one but I suspect it might because they're asking the original price, over eleven dollars more than the current XM-L2. Kaidomain might be willing to sell the lamp head alone, they are very accommodating that way. I'd want to verify first how it's made inside though, doubt KD would have the answer. Either way, a very nice lamp with a slick look and the dual control buttons are certainly a definite plus.

    Well I ask cause what amazon offers always seems to be older versions and I don't mind buying the lights there, the cells when stripped from packs and ran through my bc6 balance charger and such seem to work pretty well afterwards. Saving me from buying good cells yet. But thnx for heads up on that. Kd 2 id the same way, big through holes and single plate too. I dont mind that as long as plate goes in from optics side and not back side like kd 2

    Yeah tigris they're selling the OxyLED branded version of the whole package on Amazon for around $40. Says XM-L and the pics show it with that earlier Cree emitter. Still that's no guarantee you'd receive the original build KD used. Seems like a real crap shoot, especially as there are both XM-L T6 and XM-L U2 versions floating around. Not to mention, Amazon might be even be fulfilling current orders with the latest build, not like they always have so much as a clue. So, if neither Kaidomain nor anyone here can confirm that the better earlier model is available, I'd say best value would be to order either the solitary NW XM-L2 U2 lamp head or full package from KD. At least you'd be getting the emitters you want, and you're handy enough to improve the rest.

    BTW, think the Silver model looks a lot more spiffy than the Black, pictures on KD don't do it justice.

    Raw does look pretty slick, part of my thing with getting kd lights on amazon, I still don't have my kd order from almost 4 weeks ago. Took them 3 weeks to get my order to the postal service. And they aren't like gearbest and offer an affordable expedited shipping. And now oxyled isn't the only kd 2x option, found 1 or 2 more.

    Silver model seems to be anodized too, it's brighter and more sparkly than regular raw aluminum.

    tigris, the other two KD style clones on Amazon are more expensive than the OxyLED and both probably ship from China anyway, delivery estimate is the same ~four to six weeks with each despite one saying USA.

    My last delivery from Kaidomain took only a couple of weeks. Think a lot of delays with them just a matter of not all items being in stock at any moment. But you can email KD before placing an order to find out which sku's are available to ship right away, they're always very responsive. You might even be able to find out from them whether any of their MJ style lamps is still the original build, if you can provide enough info in simple language (easier said than done.)

    Actually the 3 I have saved are all prime 2 day shipping eligible. Oxyled, securitying just added one in the last few days then the supernight one which seems to have the oldest version. Not easy to find took me browsing everything cree light under cycling, prime eligible, to find the other 2.





    Btw Andy, what does ur driver look like, haven't found driver pics yet.

    Edit: Nvm found pics.

    Wow those sure are hard to find, tigris! But SecurityIng doesn't say which model it is save for only being 800 lumens (probably the shocking truth about them all, but just might indicate genuinely inferior circuitry here) and while from the limited specs provided the Supernight could be the same as the original KD, there is no way of knowing the truth until you get it. Also note that item is not shipped by Amazon so ineligeable for Prime or their superior exchange policy — delivery estimate still not bad even for Standard though. But as neither of these skus have garnered any reviews yet on Amazon I'd certainly hesitate before ordering, especially as they both come to more than the OxyLED, and all of them would still require around a $9 upgrade for neutral white emitters.

    Hmm my account shows supernight with prime fullfilled by amazon, same with my securitying version. I always check that, but im gonna double check on website vs my app.



    Securitying to me seems like later model and wasn't their a few days ago (my kd 2 is securitying and I searched all their lights a week ago), supernight has a few reviews dating back to release of kd 2x. Oxyled not much there either.



    Gonna drag up links try to figure out why your seeing something different than me, maybe learn a detail I missed about amazon lol.

    Update: Nope, fulfilled by amazon and covered by their return policy
    http://www.amazon.com/gp/help/custom...deId=106096011

    Hmm which one to order.... Not oxy, its only 3 mode, securitying is more expensive but I know that brand... Other one has best chance of pills and good reviews....supernight it is.

    So far what I've seen there were only two versions of MJ-880 clone. I don't know about Amazon (it doesn't deliver to my country), but I've got few from ebay and KD. Versions with XM-L leds were old design with pills and versions with XM-L2 were one plate led PCB. Both versions had same driver, but different connector (minor difference waterproof versus nonwaterproof). With both versions some sort of pills were needed to elevate leds into position where LED-DNA lenses have fit. Otherwise housings didn't have much difference and I think the consistency is much better than with most SS X2.

    Based on that I think there is not much to be afraid. Of course I might be wrong. With Chinese you would never know. ;-)

    Ah, found it!

    http://www.amazon.com/SUPERNIGHT-TM-...rds=supernight

    Okay so this Supernight sku is fulfilled by Amazon. And a good thing too, it has not gotten the best reviews by those who actually attempted to use it for any length of time. Am sure though tigris you'd be able to take care of any little shortcomings beforehand. Like ledoman says, a great lamp body no matter which version. Gold one looks pretty hot too. Only wish some vendor offered it with NW XM-L2, not worth the price and effort to me to reflow new emitters. Will let you have all the fun, tigris. ;-)

    Hell reflowing emitters take 5 mins

    Well works out I have optics on the way from leddna, just no idea when/if they'll ever show up lol.
