>>I carried a Photon 2 in my keycase for years<<

Maybe that's the problem. My "keychain" is a loop of leather thong that currently holds 7 keys,dogtag, P38, and a Strike Master miltary match and scraper*. There's no protection of any sort when I cram it into my pocket. With everything else that's in there the light was probably just getting activated anytime I climbed into the truck or knelt down to work on a rack at work.
