I couldn't find an Eveready C-whatever bulb when mine blew out. Eveready Utility Lantern is cheap and widely available. I don't think I would buy it again but I still had good batteries for it that I haven't used. I don't see this bulb being any brighter than the one that came with the flashlight, but it's ok. To extract the original bulb, you must use pliers. Unscrew the cover and twist the black plastic thing holding the bulb. At least with my flashlight, I had to make sure the bulb was lined
