[QUOTE=Giro;10669825]Do you have any recommendation on which flashlight model? DX has two with claimed 320 lumens, the UniqueFire L2 Cree XPG-R5 320-Lumen LED Flashlight - Black (2*16340/1*18650) and the UniqueFire L2 Cree XPG-R5 5-Mode 320-Lumen LED Flashlight - Black (1*18650) but they also claim only 50 minutes run time.

I gave up on the Uniquefires and sent them back again. Same problem, overdriven. I got the Ultrafire 501b and it comes with the new LED and it only draws 1.2 amps. Runs 2 hours on high or 4.5 hours on the flashing mode.
