I put in a Q5 module single mode from DX into a solarforce L2 body, and when using ultrafire 3.6V 16340 batteries. When using it, if flick it on and off a few times you can get it to be much timmer. It also happens once in a while when you just turn it on for normal use, the flicking just allows you witness it more often. normally i wouldn't care that much, but considering i'm going to use it as a weapon light, i'd like to fix it. any ideas?
