Products in the lighting control family are used for turning lighting devices such as street lamps on or off, and/or communicating the operational status of a controlled lighting agent to some controlling entity. Examples include photocell-based devices that provide a contact closure output when ambient light levels fall below some specified level, to devices that implement powerline communications protocols to allow control by a centralized agent.
