i just got corbin's driver yesterday, running a lux III red-o from a 7.2v pack, it worked great,but I got home today, turned it on and it cut out after about 10 seconds.....i removed the led, soldered the restistor back in place, threw a battery on it, and NOTHING! i got this led less than 2 weeks ago. Could this be a dud, or is my driver defective? it will light a k2 white so i know it has output so i put a volt meter on the led out of the driver and it's reading the same as the battery output--- so did the led burn out from overfeeding it? this has me pretty pissed right now and I'm about to scrap it all, it's brand new, so now I'm building into a slow burn and I'm ready to put my fist through a wall....
