Abstract
A dimming controller and system is provided in either discrete or integrated form and includes a single electronic controller device and a dimming ballast for installation in an overhead fluorescent fixture. The system functions to sense power line changes caused by the flicking of a switch between OFF and ON and controls the light dimming accordingly. The power line changes may be either changes in mains frequency or user caused switch toggling.
