I had one. (brookstone) I don't have a photon. I liked the brookstone one alot. Small and bright, but i would always accidently hit the switch. Than when I needed it, it would be dead. I spilt glue all over it and pitched it. I bought some cheap ones on ebay. Same battery combo and a better switch so it wouldn't turn on by accident. The only thing was it wasn't bright. I tried swaping out the LED from the brookstone one, but the wires were to short. The point is with the small lights that run on 2 2016 coin cells - some are brighter than others (I am guessing LED), some are designed better, and some are made better. I have absolutely no use for those lights anymore - been replaced by a LOD-CE. Way, way better and worth the few xtra bucks.
