I have a pelican Sabre light - it makes a great flashlight for around the house. For diving I have a pair of Photon Torpedos - one with an LED upgrade. All I can say it that they work every time on time. The LED upgrade turns your back-up light into a light that can be used as a primary on non-penetration open water night dives. I know this as I used mine for that recently (after my HID #### the bed on the first dive). I can't say enough good things about the construction quality of Chuck's lights. The only way I'd consider any other back-up light would be for him to come out with a 2 cell version.
