ABSTRACT:
A device which is designed to save electrical energy expended by a regular rapid start fluorescent lighting fixture having a plurality of lamps, or tubes, and a conventional ballast. The device comprises the combination of a step-up transformer, a resistor and two capacitors, all of which are mounted externally of the ballast. The device is wired in series with the ballast and one of the lamps to allow normal ballast voltages to be delivered to the lamp circuit, thereby eliminating any detrimental effects to the lamps or ballast. At the same time, the current to the lamps and consequent consumption of power by the lamps is substantially reduced to save electrical energy while providing a reduced, but uniform level of illumination.
