[alnukem]

Hi, I bought 2 Fenixs with CR123 Batteries & 3 or 4 Position switch, one failed in 4 months & the other in 6 months, & I am not that ruff on them. I want something with a position for about 60 hours in the lowest setting, but also with a regular light, Please let me know what I should buy, must be CR123. TIA, Al
