Abstract

An illumination device is disclosed generally comprising a translucent housing with a plurality of light sources and a power source disposed therein. The light sources emit very high intensity light and are arranged such that light emanates from the housing omnidirectionally in order illuminate the entire surrounding area. In some embodiments, light emitting diodes of at least 3000 MCD and wide viewing angles are employed. In certain embodiments, a housing specifically adapted for easy power source replacement and disconnection of the power source is utilized.
