Hello fellow light lovers. Last Christmas I bought 5 UK 3AA CPO LED flashlights,( 50 bucks each). Gave some for gifts and kept the rest. Good output and battery life, but not 100% reliable. Have had some failures to light, unsure of the cause. Most times light did come on after some tinkering. I had not seen anything about these on the site so I thought I would ask if anyone else has tried them. Thanks ron.
