Simple Lux Math?

Tiresius · Jun 1, 2013

Does anyone has a definitive math for lux increase switching from XM-L to a XP-G2 with a solid mass of heat-sink light? The reflector and lens will be the same.

The light I currently am preparing to mod has 41k lux (manufacturer claim). I measured 2.85a on the tail-end of the light. The guy wants to increase the throw in it and XP-G2 dedomed was what I had in mind without going aspheric.

Same drive current for both? The only way to know for sure is to do the mod and measure.

Same driver, current and power source. I do not have a lux meter so no chance for measurement. I was hoping that someone knows a definitive lux measurement but I know for sure that they change abruptly through different reflectors, lens, placement and fitment of the emitter/mpcb. The joys of an infinite amount of modifications.

Simply de-doming the XM-L T6 cleaned up the nasty rings around the hotspot. Lets hope the XP-G2 de-domed does do the same
