Abstract
Abstract A combination light, radio and clock which is designed for operation on two types of batteries, one of which is supplied by conventional alternating current. The device includes a cabinet or housing designed for mounting on a wall or resting on a flat surface, with an incandescent light, a radio and a clock mounted therein. The light, clock and radio may be utilized during normal operating periods by conventional alternating current which is converted to direct current by a transformer and during emergencies by a rechargeable battery, as well as one or more replaceable, rechargeable or non-rechargeable batteries.
