ABSTRACT:
A circuit for operating a plurality of electrical devices at a plurality of varying power levels includes a plurality of motion sensor circuits for detecting motion relative thereto and having an a plurality of outputs conditioned upon motion detection. Additionally, a photocell sensor circuit for detecting a low ambient illumination level has an output command conditioned upon the detection of a predetermined illumination level that is electrically coupled to the control circuit having a plurality of inputs.
