Finally it happened - I find this section of the forum)) I really like Alpha and the way it keeps its brightness at a high level for a long time without stepdown, like most other lanterns have it. But the time of work on 1 * 16340 did not suit me, so it was decided to make an extension tube for work with 1*16650. I had the opportunity to anodize, but bare aluminum looks better (silver and black) than two shades of black. High / low switch works fine. Perhaps the same effect can be obtained by using a flood lens in Bravo. I'll have to try sometime.

Nice stuff DS, did you have that made or is it one for a Surefire?
If it's a SF one did you shorten the tail threads? I think it's Elzetta that has shorter threads, or are they longer?
Anyway, glad the HiLo switch still works.

Well, I did it for myself, since for sale my friend-turner still cannot achieve a high surface quality, as do other artists and masters here (McGizmo and other). But he does not take much, only $ 7 apiece. We can made 1 or more pieces, if someone wants

Nice work!
Keen to do something like this for my Bravo. I've bored it, (properly) and am considering modding an old Solarforce L2 extension tube I have, so as to be able to run two 18650s. The only consideration is that Solarforce run their ID (internal diameter) at 18.85mm, whereas I like a snug fit for my Panasonic cells at 18.60mm. The 0.25mm difference is enough to introduce battery rattle, which annoys me no end.
I've jerry-rigged a twin-18650 scenario on the Bravo for testing, and at 900 lumens it's an absolute night-eating beast. The L2P with extension theoretically runs at a similar 850 lumens, and while it is still a very impressive light, the penetration distance just isn't the same. The Elzetta AVS head on full power is a beautiful thing. :drool: If it works out nicely, I'll post some pics here for y'all.
