It's a nice light, one of the nicer but larger of those coin lights. If you mean the Photon II, well, hmm, the Inova is a bit better technically but I like the Photon's smaller size and better looks. If you mean the (e.g.) Photon Freedom then it's a much more subjective question, do you want something simple or do you want a computerized light with a lot of features.

All those lights are in the $10 and up range. There are similar lights you can get that are 95% as good for $1.00 or less (example example example). So I don't bother with the expensive ones any more, I buy the cheap ones in 20 or 50 packs and hand them out like candy. They work fine. I even sometimes scrounge the batteries from them to run other lights.
