    It's huge...22x22x14, but I guess it's meant to be used in bigger lights.

    Let us know if this would work on 12V driving 3 XMLs & if it really gets 3 AMP.

    This would be better than the old P7 drivers that has 5 modes.

    looks beefy & fits mag C. I looks similar to Der Wichtel driver but cost 5 times less. Hope this works out!

    I have had one from KD, maybe not the same board but specs were similar. 22mm diameter fits well into a TrustFire TR1200 drop-in, those sold on DX with 52mm reflectors. It makes a good mid range thrower (nothing sniper style but does really illuminate far) with an XML emitter.

    Thanks for doing this, and thanks for all the testing you have done before. The results you have shared with us are very useful.

    just one question......

    since there are 2 boards does the smaller one is the controller that sets the modes?

    can it be removed to make a single mode driver?

    Kostas, usually these drivers use PWM most of them have the classic design of the buck circuit and the modes circuit. So, it is possible to get one mode.

    I know the interest here is to drive the XM-L to spec @ 3amp, but I find the 2.8A AMC 7135 boards from shiningbeam to work flawlessly. Also they are much smaller and fit a wider variety of light sizes, from P60 style all the way up to mag mods. It does not push the XM-L to max output, but I don't think the extra 200 ma will make a noticeable difference to the human eye. They cost about the same as the DX driver, although, it is only rated to max 6V input which limits battery config to either a single rechargable lion, or maximum 5 x NiMh cells.

    Either way, I'm always interested in new drivers too, so I look forward to ergotelis's test data.

    indeed on all points made, but you are missing a point...this is compatible with 2x Li-Ion batteries....a rare occurance in cheap drivers

    Correct, and that is my one gripe about the 2.8a driver from shiningbeam (link here for throwjunkie) and also available from user download which I neglected to mention (sales thread here). However, thanks to download, there is a wiring "trick" that works with 2x li-on or 2x IMR cells here which I used to build my 4 x xpg in a mag 2c here. Similar builds done by tx101 and vestureofblood.

    With download method, you can do 2 or 4 but not 3 with 2 Li-ion.
    To squeeze out a triple XML on Mag 2C, I had to import a new type of IMR batteries from China.
    http://www.candlepowerforums.com/vb/...h-3x-IMR-22430

    If the DX driver can drive 3 XML, it might give a nice new option for Mag 2C?
    I just wish it had Hi/Mid/Lo instead of Hi/Lo Strobe.

    If it can only drive single XML, then it's not as exciting, because I'd rather prefer Mag 1C with single IMR 26650 4000MAH + 2.8A 8x7135, plenty of run time & better modes with H/Mid/lo.

    I've got these drivers running off a 12V 105Ah DC Battery as per this post. The driver was not used in the build at the start of the thread. Towards the end I have a photo of a larger set of lights. I used the new driver in those.

    No idea on actual power out but they are definitely brighter than driver used in the small light at the start of the thread (2.4A). They ran well, did not get hot that I could notice. The modes are stupid though. I just want low and high - strobe on the finished flood lights is ridiculous lol.

    Too bad they don't have them with single mode and provision to put a dimmer pot, better yet with a dimmer pot already soldered and ready to go. Not really for flashlight use but for someone wanting to build a lantern/ lamp or perhaps a video camera light that a dimmer is a must.

    Confirmed: Removing the smaller PCB makes this a single mode (HIGH only) driver.

    I have tested it last week, it starts as 2.8a, but gracefully goes down to 2.7a. Input was 12v @1A. Output 2.7A @3.8v for a P7.

    Any idea how much power low draws from the battery? I'm trying to decide on this for a bike light but two XML emitters will only be lucky to get an hour from my battery pack.

    I'm using one in my 2-piece super bike light. It powers 3-in-series 4p MC-E from 4 D-sized LiFePO4 cells. Those three MC-E have higher Vf than 3 XM-L would at the same drive current, but the principle is exactly the same.

    I considered using this driver. But decide to use the sst-50 driver from dx. Drives the xml to around 3.5 amps.
    Very bright in a maglite. Also the modes helps with the usability of the mag as its just too bright up close.
    I like H M L modes but the strobe and sos i could do without.

    Any other relatively inexpensive drivers for XM-L with a wide input voltage range >12v for automotive environment? We have tried to the DX driver over at hidplanet.com and they seem to have a high failure rate.

    Sku 26110 has been reported to work good from a 12v source. Can be modified to give 2 amps to the led. Not fully driven but will work. Read the reviews at DX for modification for 2 amp output.

    I've tested DX3256, another AX2002 based buck driver, out to 18V with good results (stable operation). I've also mod'ed DX3256 up to 2A. Efficiency seems to suffer, though, at that level (around 78% IIRC). The driver seemed better at around 1.6A, where it was around 82%.

    this driver from dx and 3x 25500 Li-ions should bring one xml to full brightness, am i right?

    can someone please confirm this, then i will sent my order and complete my m@g mod. thanks

    Here's a pic of the driver the OP is about, modded for single-mode with a 1k-ohm pull-up resistor and with the edge filed. It just fits inside the cavity of the OLD style DX 52.8mm MOP MC-E reflector with base (skus 39409 & 17384). They've since changed the base to have a taller and wider cavity, but less brass to draw heat with.



    Current output measured with a clamp meter is 2.7A. I didn't measure output of the various modes before modding for single-mode.
