All, My 6 month old Nitecore P12 fell of the nightstand, a relatively slight fall onto carpet. When I went to use it again it didn't turn on. I charged the Nitecore 18650 battery and tried it again with no luck. After some time playing with it the light appears to only function in the low setting. So if you turn it on, which unless its in low, is a total guess you can cycle it through the modes and it will be off for most clicks then come on with a very low output, probably the 1 lm setting. The voltage reads, from the flashlight, at 4.1 or 4.2V. I haven't put a DVM to any of it to see what is/isn't working, but I don't have anything to compare it to previously. I also haven't put CR123s in it either, ever for that matter. I have an authorization to return it for a refund, but if I can fix it easy that would be great. I really like everything else about the light, when you know it works. Thanks in advance for any recommendations!
