Great pictures and review, ernsanada! (As always!)
I've had several of these 602C's (Luxeon version), and had battery issues with every one of them. After a bit of head scratching, I discovered that the batteries were running out of downward travel, preventing the battery tube "shoulder" from properly contacting the pcb. Some batteries would work ok, some not at all. The fix is to take the battery tube spring out and trim about one-half coil off the bottom. (Note that I said one-half coil, not half of the spring. You're only trying to reduce the total spring height by about 1/32" at a time). Some need a little more, but don't take too much off or the spring will lose it's friction fit. If that does happen, just spread the bottom coil out a little and press the spring back in. This has fixed all of mine. I even had the same problem with the B3, which uses the same housing. Hope this helps!
Man, that emitter mounting job is scary! I hope they don't make all of them like that. Check out the third pic in this link (one I just sold)...that's how it should be done! Shame on Ultrafire...LOL. https://www.candlepowerforums.com/threads/172843
I took off about 1 coil, still no good with nimh.
