Decent deal on 18650 based light, 1200lumen is a bit doubtful, its about as bright as the energizer on turbo mode. More throw vs flood. Dual led so heat should be less of a problem.
5 modes, though strobe/sos are superfluous
The usb port is revealed by the screw collar and it has a very large headband.
