Abstract
An illumination system verifies whether one or more aspects of an output signal provided by a photosensitive transducer fall within a threshold of an expected value for the aspect. The aspect may include a sunrise time, a sunset time, a dawn time, a dusk time, a solar noon time, a solar midnight time, or similar. Upon verification the illumination system uses a microcontroller to adjust one or more output parameters of a solid-state light source responsive to the output signal provided by the photosensitive transducer. Where verification is not possible, the illumination system uses the microcontroller to adjust one or more output parameters of the solid-state light source responsive to a schedule.
