I agree with you. Spare SMO reflector will be available.
Dark-cross of XHP70 can only be seen when you are close it to a white wall. When using it outdoors, the dark-cross can barely been seen. We did a light-OP finish to the reflector in order to save some lumen-loss.
I imagine they use a battery solution like jetbeam T6. More easy compared with battery holder but a 4s configuration would be better for 12v leds (xhp35).
Anyway nice approach
Yes liking it a lot, 8mm thick emitter shelf, bypassed copper alloy springs, 40mm DTP emitter board, whats not to like!! :+1: 18awg leads for the XHP70 would be better, IMHO but at 6 amps 20awg will do, unless you plan on pumping it up a bit more?
Use a premium thermal paste/grease, make the mcpcb pocket tight to hold centering the LED and screw down the emitter board for better thermal transfer, and also not to allow the board to twist and possibly cut the LED leads, would be a couple other suggestions…if your not doing this already?
I wonder what it’s like to hold this light. It looks like it’s head heavy, so you have to grip it in front of the buttons where the cooling fins start to keep it balanced. Is it comfortable to hold in such manner for a long period of time…
I like the heavy block vertical (Fins) heat sink(s) at and below the emitter shelf, having a integral shelf, this should do well to dissipate a substantial amount of heat! Hopefully the inner cavity walls are thick too!
