Hey all, so i received my Liteflux LF2XT today. Everything about it is great, however there is a major problem. Everytime i turn off the light for more than 6 seconds, the light ceases to function anymore unless i unscrew and screw the head back in. The stainless steel tail cap, brass ring, and head are screwed in enough. Threads are clean, multiple batteries were tested. Still the same problem. I have already contacted LEDCool about this (Crazy fast response by the way) but he could not come up with an immediate solution to this. He said he'll get back to me on monday (I'm guessing he's contacting Liteflux). But in the meantime, has anybody else experienced this problem?
