Thanks rafowell for the reinforcement. Strange you should mention the Photon light. I don't always ascribe to the "One is none. Two is one." philosophy. But in my urban existence, emergency lighting is so critical a requirement that my keychain always has a second, backup flashlight. My choice Is a Photon Freedom, with a yellow LED, mounted backwards in its clip-in holder, to prevent an accidental "on". The whole unit is X wrapped in the supplied neck lanyard. This duo has served me well for many a year.
