Pocket Rocket 1*16340 xm-l t6 @ 3.0A build help - just trying for shock and aw

Hello all, new here, I pretty much have things figured out, just wanted to make the run through and have veterans add some experience my way.


host: (have a few but just ordered what will be my smallest)

LED:
xm-l t6 on 16mm star (trying to find some spare copper to make a new star)

driver: (very flat so i can stuff some more copper under the other side of the pill)
(if i cant get 3.0A ill replace or add a resistor in parallel)

battery:
AW IMR16340

Any idea on optics? doubt any convex lens that small exist, any reflectors?

This is only for that shock and aw effect, I imagine after a few seconds this thing will start to become very hot

Welcome to the Forums!

Having build a few little rockets I'd just like to point out that asking 2.8-3A from a from a cell that small needs to be a limited to burst use. You will be exceeding the 4C discharge rate of the cell putting you into unsafe battery territory. Might I suggest a 3 mode driver for usability in the lower outputs while still having crazy bright high.

I found some spare copper for a snug for a project like this and yes it does get very hot quick on high, but for pocket rockets it works. I played with some Carclo optics with the XM-L and didn't like how floody it got and how square it focused the beam.

I look forward to see what you make.

thank you for the tips, exactly what i was looking for.

it is a lot of stress on the battery but i hear aw imr 16340 handles up to 5c, anyways cant keep it on for much because the heat would kill the led

thats a good site, everything shipped from new york? i like that driver a lot might as well make the light functional lol.

where did you get the copper slugs? i have a bunch of extra computer heatsinks, some copper some aluminum but nothing to mill them. my friend has a warehouse full of machines and tools, im sure he has something for milling.

Also is there any way i can make this flashlight even brighter then a xm-l t6 @ 2.8-3A?

Well, three XM-ls ran at about 1A each should give you more output compared to a single die at 3A (maybe even give em a little more than that?) Should be like 1100 emitter lumens vs 900 or so?

The standard reflector should work, the xml focuses ok in an xre reflector. The low vf of the xml helps when running off a 16340, I built a similarly sized xml pocket rocket using a qtc pill for infinitely variable output http://www.candlepowerforums.com/vb/showthread.php?310788-Fun-with-XMls-in-cheap-hosts.

well I have done a similar mod myself with the very same materials....

see this....My baord is drawing 3.3A at the start and drops considrably once the flashlight gets hotter...total runtime is 10-12 mins...
