Bombelman: thanks, sanded 1-2 mm off the bottom, the REAL pain was sanding around the outside so it would fit.
cryhavok: not sure, is yours really freakin' bright? i am going to do a LR5 with cree, flupic, and mcr17xr when the flupic gets here. maybe i will post some comparison shots.
Can one have too many small, multi-level, bright lights?
