Abstract
Abstract A recessed lamp reflector has an integrally formed trim ring and fluorescent tube receptacles on opposite sides of an upper portion of the reflector. Fluorescent tubes extend across and downward, in the reflector, crossing at a central point within an upper portion of the reflector. Ballasts are mounted on an upper surface of the reflector between lamp receptacles. A cover covers the ballast and receptacles and interconnections and rests on top of the reflector.
