Vinh of sky lumen has a manker E14 on his site with the xpl hi option. On his website the ANSI lumen output is only a few lumens over 3000. Shouldn't the output of a quad XPL HI be over 4000 with a fresh 18650 battery?
Battery has problems with delivering 12Amp. Heats up fast, and ANSI standard is messured after 30 sek on. And lightloss on the tir optics. Resistance in wires driver springs. etc. It all adds up.
