Mine don't whine when i use 10440 cells. Little brighter than with normal cells, but the no whine is the best bit. I think it's safe to use unprotected 10440 in this light, so that's what i feed it.
sounds like you use cui and has memory turned off and the first mode programmed as medium?
Mine had the same flickering issues, retaining ring was the problem, came loose all the time. light went crasy.I think all the on and off flicker, might program it to all sorts of random settings. One big uber tighening on the head and tail, and it havent had a problem since. Even went trough the washer on full program, came out working perfectly. Clean but dinged...
