Abstract
A networked light control system includes light sensor circuitry that includes plural light sensors configured to sense an ambient light level, a control unit configured to generate a control signal that activates or deactivates one or more lights in a network of lights based on the ambient light level that is sensed by the light sensor circuitry, and relay logic circuitry configured to open or close a relay or a solid state switch for activating or deactivating the one or more lights based on receipt of the control signal generated by the control unit. The relay logic circuitry is configured to control the relay or the solid-state switch responsive to a failure in the control unit.
