Here's more info. Altho one could offer this as a complete light, since the few skills I have lie in the mechanical world (not electronic), I've been assuming that if this project has legs, I'd sell the bare tubes (anodized, of course). That way, you electronics guys could use whatever LE and emitter you like.
Cree? Sure. I, too, am very impressed by the A19 Cree lights the Shoppe is selling, altho I'm not convinced that Wayne's not pushing the emitter so hard that reliability might suffer (but, then, I don't know about these things).
The McR to LE distance is adjustable via the assembly process.
Assembly: from the front, screw the LE in too far (viz., below its final location). Then drop in the McR, lens and o-ring, and screw on the bezel. Then, coming in from the rear, screw the LE forward until it touches the McR. This takes a bit of fiddling with makeshift tools, but if this goes to production, the correct (very inexpensive) tool could be included with the body.
Drop in the 18650, screw on tail cap, and fling some photons.
In some cases, the (+) terminal of the LE won't touch the battery, in which cases I usually build up the LE terminal with a tiny bit of solder. A small magnet works, but that worries me as to possible shorting.
I would drill/tap the body for the standard Ti clip the Shoppe sells. Or, I have my own thoughts about clip designs.
The obvious drawback to this design is that there are no options for different heads, as there are with my other LeefTube that uses standard SF-E, Aleph threads.
I made a mistake with this prototype -- the knurling should stop about 1" behind the front. IMHO, it looks strange with the knurling going as far forward as on this prototype. A small groove could be machined into the tube, abt. 1" back from the front, to simulate the traditional separate-head look.
This light uses the world-famous LeefRing for a lanyard, as well as the LeefGrip (on the market in a couple of weeks) to allow the stogie hold.
I think I need a real job. :laughing:
