Abstract
A fluorescent lighting control system providing automatic and/or manual adjustability of the arc current(s) in one or more fluorescent lamps to permit operation of the lamps at less than rated wattage, and its concomitant luminous flux, in interior building spaces where full light output of the installed lamp(s) is rarely required particularly when daylight components are present. The goal(s) of this invention is to provide means to reduce wasteful electrical consumption in buildings and thereby reduce operating costs and gain the attendant benefit of dampening the increasing need for more electrical generation with its concomitant environmental pollution problem.
