i just purchased the doug ritter photon II, so far it looks like what i need. small, hands-free, and a decent way of keeping it from turning on by accident. my psk is too small for most of the tube style lights, so this smaller LED should do the trick. since i mostly camp and backpack, i always have a bigger light anyway, my psk is only for the unfortunate incident where i might be separated from my gear. since my psk is only intended for an absolute emergency, the photon should be perfect. thanks for all the suggestions, i know i would've wasted alot of money if it wasn't for this place.
