A fellow BLF’er modded it for me 
I wanted it to use only ONE cell (shorty version) and so it’s using the standard Nanjg driver
with added 7135 chips.
You could use the original XM-L2 emitter (dedomed) but it wouldn’t throw as far as an XP-G2.
Others have achieved around 220-230kcd but I didn’t want to go the full 5 amps because of heat issues.
I’ve used it now for about six to eight months and no issues.
