ABSTRACT:
A limited power, gaseous discharge lighting system, particularly suitable for use with suspended ceilings and for safe installation without shock and/or fire hazard and for rearrangement by non-electricians without special tools or experience, the light output of which is controlled by an electronic controller which responds to the ambient light available. The system uses non-armored flexible cables to supply individual relocatable gaseous discharge lighting fixtures and dimmers, and the cables are individually plugged into receptacles which furnish power strictly limited to permit the safe use of the cables, plugs and receptacles. High frequency operation permits efficient operation with rated light output and an electronic controller furnishes additional versatility and economy.
