Guys, just got mine. First comments:
The bad ones, Silly PWM,silly disco modes, i don't like the button in the back, wish it was on the side. no UCL, can't find either one!
The good ones, excellent quality for the money and for a trustfire, too many battery configs available, good heatsink design,excellent square threads, generally nice design.

My new lumen leader! I posted the others for comparison, to show how other flashlights perform in the same test method. Trustfire tested on 3 AW 2900, 2,17amp draw. Are you kidding me? I will redo and redo the test to be sure, but this is sick, what can i do more?
The flashlight starts@1sec@ 2430 lumen and gradually falls. Middle level is 1460 lumen and the lowest 310.
