ABSTRACT:
A lighting fixture 12 for use with fluorescent lamps 2 can be mounted in an opening in a suspended ceiling 4 or it can be supported below a ceiling. An integral ballast subassembly 14 is mounted on one end of the lighting fixture 12 on a ballast end support 64. Commoning lamp sockets 62 are mounted on a separate end support 84 on the opposite end of the lighting fixture 12. A ballast capable of energizing fluorescent lamps 2 in series is used so that the ballast subassembly need not be connected directly to the commoning lamp sockets 62. The end supports 64 and 84 can be mounted on opposite ends of a suspended ceiling opening 10 and a thin bonnet or hood 98 can then be positioned above the end supports 64, 84 after the ballast subassembly 14 is mounted at one end. The ballast subassembly housing 16 includes two separate compartments, with the ballast circuitry being housed in one compartment 28 and with the power wiring being positioned in the other compartment 30.
