That light has the same build as the double uv group buy light that I hosted last year (and had an unhappy end) (gb=closed) Only 50 lights were delivered and sent out, *BLF special* Romisen 365/400nm 2xUV SSflashlight, gb with Tinywind . Here’s a teardown of the light, on top of the SS that prevents spreading of the heat, the heat path from pill to shell is also bad NEW TrustFire TR-DF010 CREE XHP70 2 Models 1600LM Diving Flashlight $69.29 Shipped - #253 by djozz . Despite that, the light gets away with 1.5A to the led, for about 250 lumen for a XP-G2. But I doubt you can hotrod this light.
