Abstract
A system and method for detecting light fixture failure and for enhancing energy efficient operation of multiple light fixtures. The system includes multiple light control modules and a gateway. The light control modules alert the gateway of a bulb or ballast failure based on light fixture power consumption. The light control module can indicate a sudden failure, a slow failure, a striating failure, a stuck relay failure and a start-up failure. The light control modules can include a photo-sensor and an occupancy sensor for measuring brightness and occupancy, respectively, in the vicinity of one or more light fixtures. The gateway can distribute operating instructions to the light control modules based on changes in the ambient temperature and based on the power consumption of nearby light fixtures.
