ABSTRACT:
A fluorescent luminaire, of the suspended overhead type, is constructed with the lamps of the "U" type having both electrical connections at the same end so that the lamp forms a cantilever suspension from a central housing. The ballast means is formed perpendicular to the lamps and placed in the central housing to concentrate the weight there and separate the heat-generated there from that generated by the lamps. Translucent/reflector sections and baffle means extending from the central housing are made of a lightweight plastic material. To assist in starting the lamps and for support, a metallic reflector or support extends adjacent to and parallel to the lamps and is grounded at or within the central housing. The reflector/translucent means and lamps are arranged so as to eliminate bright and/or dark spots.
