Hi guys,
I put a 5W HD in a P60 reflector and M2 bezel. Lot of work! I saw this post a couple of days ago but without a buck/boost driver like a wizard or what SF uses in the KL1 and 3, 3x123 cells will overdrive a 5W Luxeon. I know some of the overdrive and direct drive masters can sort through this but not this guy. Seems to me that with 5W's, you want some throw and I have only seen this with a turbo head; the smaller reflectors don't cut it, IMHO. The turbo modules I've made only work on 2 cells.

EDIT: If anyone can do a SF 3 cell flashlight justice with a 5W Luxeon, my money is on PK and team. He stated on the forum a few months back that he was working with 5W Luxeons.
