Abstract
Abstract A utility lamp has a tubular handle for containing a bulb receptacle connected to a cord extending out of the handle and terminated by a connector. A bulb cage or guard is removably clamped to the handle to protectively enclose a bulb inserted in the receptacle. Formed integrally with the bulb guard is a cord storage section about which the length of cord extending from the handle can be wound. A stand is formed at the free end of the bulb guard permitting the utility lamp to be stood on end on a horizontal surface. Also, a hook is swively mounted to the top of the bulb guard so that the lamp can be hung from an elevated projection and a magnet is mounted to the cord storage section enabling lamp to be suspended from a ferromagnetic object.
