I have a Fenix E1 that i purchased in November from Fenix Store. It now does not work for some reason. I had been carrying it on my key chain since i got it. I came home from work one day and noticed that the light had come on in my pocket the light was very dim it had probebly been on for a few hours. So i put in a new battery and all was nice and bright again. The next day it will not come on at all, it did not flicker at all. Just went from nice and bright to nothing. Any ideas on the problem or am i just out of luck
