I've used the Photons for years and have been satisfied, but at a buck a piece I won't be buying any more Photons. I like the slide ON/OFF switch for use in PSK's. At a buck each I was able to put one everywhere I might need a light. So now all the FAK's have one and the BOB's have one snap linked to the outside. I haven't tried any of the lights that are $2.00 each, the ones at $1.00 seem fine. My co workers prefer the the buck lights over anything else I showed them. CountyComm also sells a small strobe light for $1.00 each. Next time I open up the PSK's for a re-do I may include the small strobe light.
