I just upgraded my backups to Chuck Noes' "Photon Torpedo's" They are 3-c cell lights. I got just the body's without bulbs and put MAL LED's in them. They rock. Very white light, long burn time and solid as a rock. Twice the wall thickness of others. Double O-ring seals. About $65.00 for the body and $56.00 for the bulbs. Well worth it.
