ABSTRACT:
A fluorescent fixture housing is preferably molded of a thermoplastic material, and includes a base portion, a pair of longitudinal sides and a pair of opposite ends. A pair of lamp holders are mounted to the housing on opposite ends so as to receive and hold a lamp therebetween. A pair of electrical connectors are mounted to the housing and lamp holders, and are electrically connected to the lamp holders to supply power to a lamp mounted between the lamp holders. Electrical conductors are mounted to the fixture housing and are connected between the lamp holders and a wiring harness, the wiring harness being removably connected to a ballast. The wiring harness is mounted to the base of the fixture and the ballast is slidably interconnected with the wiring harness to affix it in position. In a second embodiment, the wiring harness remains free from the fixture, and the ballast is removably mounted in the desired location on th base portion of the fixture. In a third embodiment, the wiring harness is molded integrally with a lamp holder and electrical connector at one end of the housing, so as to eliminate any discrete conductors therebetween.
