Yeah sac02, I kinda wish Iād followed what Iād been doing and done one thing at a time and measured in between. The 18Ga wires probably helped a little but I wouldnāt think thatād be a big jump. The FET made a difference, more so than the wires, but in the end I think the XP-L2ās were the major change. 700 lumens between a modded XP-L light (for each emitter) means 2100 lumens easily right there in the emitters. Tom had seen around 7100-7200 which was 1800 lumens per emitter, looks like we can attribute most of the gains to the next gen technology.
Cheap USB (5mm jack plug) 14500 light running NarsilM_1.2
I sacrificed the charging plug and add 10mm Neodymium Magnet
Bought from AE for $5.19 each
Got a link ?
Looks like a good mod project
Thanks
Donāt know if you could call it a mod, exactly, but Iām very very happy with DBC-06.7ā¦ 24 hours of lathe work, then final assembly including building an A6 driver.
The emitter is a de-domed XM-L2 from MaxToch, clean job on the de-dome they did. Itās new gen, so it only pulls 4.61A but makes 1652.55 lumens. Final tuning it does 815Kcd for 1974.57M throw, which is 1.122 Miles!!!
I made the tail cap (more of a plug) the body (from a single bar of 2.75ā 6061) the reflector adapter (from a 4 1/4ā bar of 6061) and the bezel (also from the bar of 4 1/4ā 6061) The copper pill is 35mm dia and 35mm tall. Cell is the TrustFire 32650 by design, the plug in the tail has long threads to allow the use of anything from a 26500 to a 21700 or 26700, even the protected variation of 32650 works. Lens is a custom order 3mm thick 104mm UCLp from Chris at flashlightlens.com.
I went with an oversized variation of the small 18350 light I built last year where the battery tube looked like twin thread spools stacked, this allows cigar grip even on this 1234 gram light!
Edit: PS, if you think turning a 4 1/4ā bar of 6061 on a 5ā chucked Grizzly 10x22 lathe is easy, youāre sadly mistaken!
Wow Dale , what a beast !
Did you use KD 86mm reflector ?
The hot spot is actually smaller than what shows in that last pic, the tiles in the picture on the wall are 12ā square, the hot spot is about 8ā at this distance.
Not exactly sure where the reflector came from George, itās bigger than that though. A friend sent it to me and laughingly said see what you can do with this! He said there werenāt any more and the mfr quit making them. I was planning to build this light already, had the battery tube bored for the 32650 and was intending to use the reflector out of my Olight SR-90 Intimidator since I have the Lum 5-90 in that light. I think thatās what inspired my friend to send this one, going big go all the wayā¦ lol
I was talking with another friend with machining experience about the sheer size here, I only had the 4 1/4ā bar and it wouldnāt be big enough to machine a head for this 98mm reflector, so he said why not just use it as a stressed member, like Ducatti does their engines? And so I did, threaded the reflector to fit the machined body part and bezel. Out of the ordinary, but then, itās no ordinary light.
So I guess I modded 2 bars of 6061 into a flashlight. hahahahaha
Edit: This pic should show how it all started, the full sized bars are pieced together for testing of an emitter inside the reflector. I used my power supply for this test, but you can see the sheer mass of aluminum I had to carve away, hence 24 hours on the latheā¦
Very nice
Thank you CRX, appreciate it.
Sure has been a black hole for my time. lol
Thatās pretty neat there Dale! Your machining skillz are off the hook!
i love that thing ! well done!
Thanks Kawi, appreciate it, coming from someone that knows real lathes!

Excellent machine work!
The last picture kind of remind me of the Statue of Liberty torch.
Couple of beamshots from DBC-06.7
DBC-06.7 at 610 yds to the barn, 1st shot is at 28mm 1/2 sec exposure at f/5.6 ISO1600, second is same settings, but zoomed in at 112mm.
Just look at that big spotā¦ Awesome !
George, look at how the hot spot throws a shadow onto the building from the tree between me and the barnā¦. the tree is 296 yds from where I was standing and 315 yds from the barn!!
The hot spot probably looks larger than it really is because I couldnāt hold the light steady in the 1/2 second exposure. The meds Iām on for nerve pain make me shaky. It is what it is.
Hereās a shot where I mounted the light on the tripod, same settings. I donāt like the lower light position as much as the overhead shot, but it is more stable for sureā¦
That was interesting . I guess it will light this barn even from 1000yds .
What is the diameter of the reflector ? I would guess itās over 85mm to give such a throw on a xm-l2 !
97.5mm, opening.
