Abstract
Lighting devices are configured to communicate with one another and with external systems. Sensors located at such lighting devices communicate with the external systems and with others of the lighting devices. Lighting is controlled to maintain safety, to drive customer traffic within a retail facility, or to conserve energy. An application programming interface provides a common mechanism for control of various lighting device types.
