As for the difference in driving amps: I didn’t want to drive the nichia very hard and therefore raise the vf above what the battery supplied. The xp-l and xm-l2 use the highest current 7135 driver with all the chips on one side. And I used the 2800 mah driver for the mt-g2 because thats what the “zener diode mod” directions were written for.
So it is optimum for all? I though xm-l2’s were usually driven harder. I’m not at all up to snuff on this stuff though. The beamshots look great by the way. I will have to do some research on the mt-g2 and xp-l. Are there stock lights with these emitters?
I guess you could say it’s the optimum current. They could all be driven a lot harder, but these currents seemed right to me to balance brightness, runtime, and heat (sans the mtg2, that one still cranks out copious amounts of heat)
