MY TESTING: By using brand new LG 3500mAh 18650's, rated for 10A continuous each, the SkyRay King produced a calculated 11,103 lumens, light was measured using a Extech 407026-NIST light meter through a diffusing box(so that overall light output is measured more accurately by the light meter.) I measured the lighting level(lux) and energy consumption of the light, then swapped out the power supply/energy meter to the 4 x 18650 LG 3500mAhs, and the light output went up 14.61%(86W), calculated ~11,301 lumens.
