Abstract
An emergency lighting fixture with backup battery power for illuminating aimable lamps or a plurality of lamps mounted in a single housing in response to loss of power. In the preferred embodiment, the lighting fixture has three independently adjustable lamps mounted within a single housing. The lamps are adjustable about vertical and horizontal axes for maximum aiming capabilities. The housing is preferably an explosion proof housing with a glass globe for mounting in hazardous locations or areas. The glass globe allows the lamps to be aimed through 360.degree. so that light transmitted by the lamps can be aimed to a specific area adjacent the lighting fixture. The lighting fixture also preferably has its backup batteries mounted within the housing along with a charger for maintaining the batteries at full charge.
