I don't have a photon, but I use an Arc AAA with a clip to my hat and it's as least as bright as my best, whitest Pelican. The Pelican L-1 has a nice flood for close up work, especially if you luck out and get a real white one and the clickie is more convenient than a twist head but the clip is the wrong direction so you'd need to keep it at hand or on a lanyard. Also, the runtime isn't as good as the ArcAAA's, the batteries are more expensive & harder to change in the dark, and I don't think it's quite as water resistant if it takes a dunking, though neither of them float so that may be a moot point.
