You can use a pcb for xp-e with an xp-g led.
I modded my fenix E21 that has a xp-e R2.
Removed the (glued) head with some difficulty, then removed the pcb with the xp-e, removed the led, reflowed an xp-g, and now i have a nice neutral xp-g R4 flashlight! Like LD25!
the XP-G and XP-E looks to be the same dimensions and everything, just wanted to comfirm that its ok to do.
deadrx7conv, thanks for the link... ill probably get some of those.
btw, i love mazda rotaries... i used to have a turboII. and a rx3, but sold it before i could finish restoring it... a regretable mistake.
