P60 aspheric

[Andrew_adams]

So I have a solarforce lm2, ahorton lens and spacer and a xre@ 2.1 on a star powered by a efest 18350 imr after I took the dome Off I was getting ~35k lux. I'm pretty pleased with
the number considering its so small. But I can't help but want more. I was
hoping someone might have some tips to get some higher numbers? Will copper mounting help much?

Yeah, Vinh has driven XP-G2 up to 6ma by mounting on copper, without seeing any tint shift.
1 other has done up to 3ma with copper mount as well.
