1. A lighting control system comprising:a lighting control component with a microcontroller and a first group of circuits and a second group of circuits for controlling the application of mains power to loads;
one or more loads operatively connected to the lighting control component;
a light sensor operatively connected to the lighting control component, the light sensor producing a first signal when it senses light levels above a predetermined threshold and a second signal when it senses light levels below the predetermined threshold; and
wherein the microcontroller is operable to reduce power to the first group of circuits when the first signal is received and restores full power to the first group of circuits when the second signal is received.
