Opening the head/bezel of the L1 is a little involved, why not bite the bullet & contact Milkyspit :thumbsup:
Milkyspit = L1 mods. He's the ninja master.
What direction are you thinking of going with this L1. Maybe the mod gys will better be able to help and PM you if they know what you want.
EX:
Old 4 side L1 body can be made to fit AW 17500, AW CR123, AW 17670 ect.. What do you like?
Keep the XRE-R2 Optic or go reflector?
Put SST-50, MC-E, K2, P7, SST-90, ect.
Then there is the heatsink issue. Are you wanting to keep the stock heatsink? If not then you can ask for someone with those skills too.
Good luck and post some pics when you get it finalized:twothumbs
Hey, I was thinking of modding my Four flats L1. But as someone else said, they are hard to open. What kind of emitter were you thinking? I might go with either a Lux K2 or a Cree XPG.
