I recently purchased a Ultrafire C8 (Cree XML-T6) flashlight from amazon. Obviously I realize that this is essentially a throw away light but I am fine with that. It is a great flashlight that far exceeds most of the far more expensive flashlights I have encountered when taking into consideration cost. The only issue I have with mine is that the mode memory doesn't work at all. Every time you turn the flashlight off and back on it proceeds to the next mode. I was wondering if there was any chance of being able to pull apart the driver and fix the issue, though I assume not. Otherwise I will just buy another one. Thanks.
