ABSTRACT:
A system and method for altering the amount of electrical energy supplied to a plurality of fluorescent lamps, has a first switch connected in series between a source of electrical energy and a plurality of lamps connected in parallel. The first switch may be a simple ON-OFF, single pole- single throw wall switch. A second switch is connected in series with less than all of the lamps and is an electrically actuated toggle switch which responds to actuation of the wall switch. Multiple actuation of the wall switch permits turning all lights on or off or some on while others are off.
