ABSTRACT:
Step dimming of a fluorescent lamp load through sensing of power line interruptions generated through the toggling of a switch. The number of power line interruptions through toggling produced within a predetermined period of time identifies the level of dimming desired. In the event that interruption of power to the ballast exceeds the predetermined period of time, the lamp load will be reset to a prefixed level of illumination once power is restored.
