Abstract
A compact illumination unit is configured provide illumination during a utility power failure. The compact illumination unit includes a housing structure, a battery supported within a battery compartment of the housing structure, a conductive base coupled to the housing structure and a number of light elements supported by the housing structure. The illumination unit further includes a circuit assembly coupled between the light elements and the conductive base to supply power to the light elements using power received from an external power source via the conductive base. The circuit assembly is further configured to supply power to the light elements using power received from the battery during a utility power failure.
