it had crossed my mind to open the reflector base up to 22mm J)
I tried to get a spare L2 reflector from a couple of sources so I could open one up a little.
The other option would be a custom arrangement to lift the LED higher off the board - either a custom pill, or maybe a small copper square stacked between the board & LED.
Anymore updates on this one? 
yeah one’s built and in the hands of its new owner. one’s assembled but needs the emitter out and dedoming.
I like xp - g2’s at 5a lol
Did you ever get any comparison shots? Earlier on you mention XM-L2’s as well?
