lightmalls - don't do it!!!
bought a trustfire ak47 torch from them. Big mistake, not original trustfire, led driver board held in place with masking tape, two blobs of solder put on board to make some kind of contact to make torch work. leds supposed to be driven at 8.5amps by driver, wiring so thin that 2amps would be pushing things to the limit. marks on glass which I managed to polish out, o ring seals fell apart when unscrewing torch to put batteries in, due to no lubricant on them. Please do yourself a favour and stay away from this hopeless firm.
