So the reason you guys are sticking with XHP35 instead of 50 or 70.2 is throw as opposed to absolute power? I do like the idea of a 125W single LED flashlight though … Does anybody have any links with the 125W test?

Definite throw. The XHP35 HI might be the best stock LED out there for throw. The only other stock LED's (not dedomed) that can compete are the XPL HI and the OSRAM Oslon Black Flat.

With my Convoy L6, I measured 18A at the tail with a XHP70.2 using a triple channel FET based driver runing NarsilM. Since the CREE XHP70.2 data sheet only shows up to 4800 mA on the Vf curve, I would guess Vf is at about 6.4V at 18A, therefore watts would be 115 watts (6.5V would be 117 watts), post #94 here in the XHP70.2 thread.
