how sbout a secret mode that goes past the emitter specs, IE from a max of 3a to a new max of 4a? (don’t be afraid to go over the current rating, xm-l2 have safely gone to 7+amps and survive, while XP-G2’s can make it past 4 amps.)
XM-l2 U3 bins?
some of the more preferred tints around here are t6-3c, t6-4c, U2-1A
Direct thermal path (DTP) copper board
IF YOU HAVE TO INCLUDE BLINKING MODES MAKE THEM HIDDEN!!
A low low mode (.1 to .7 lumens)
high PWM (true constant current would be better)
I prefer a good deep carry pocket clip, (head down) But that’s my preference.
If 18650, 2x16340 (8.4v) support would be nice
a red mode would be cool too, but I can only imagine it to be feasible if you were using a TIR
try to keep everything simple. If I bought it, I expect to be able to hand it to anyone and have them figure out how everything works relatively easily. If I want fancy, I can just ask ttrev3 to build me a light.
tailstanding, and para-cord lanyard holes would be nice
I like my smaller lights to be suited for more close up to midrange distances than being throwers.
if you are going to implement charging, make sure it charges with correct CC/CV. A li-ion packs a lot of power, and putting that in a sealed metal tube, then incorrectly charging it is playing with fire.
If you need any advance product testers, I know some who might be interested
