44.6mm head, aspheric XM-L, 18650, 3 Modes

I got mine. I really like it even thought it was driven at 1 amp on high. I subsequently got it apart and rammed in an ultrafire p60 xm-l (w/o the reflector) that I wrapped in copper foil. Seems to be OK in there. I got it pretty tight and thermal transfer seems good. I have not done a current or lux test yet.
