The light fixture includes a surge protection device with a monitor that indicates when surge protection fails. The light fixture includes a power supply monitor configured to collect real-time AC current, voltage, and power factor measurements from a power supply. An operational characteristic monitor monitors an operational characteristic of the light source, such as current consumption, wattage, real-time temperature, a brightness level, and/or an efficiency of the light fixture. A communication device positioned between the power supply receives information from the monitors and wirelessly transmits information regarding the monitored operational characteristic and information and/or power supply measurements to a remote user equipment. The communications device may also receive control instructions from the remote user equipment for controlling aspects of the light source. ## Claims ### Claim 1 A light fixture monitoring and communication device, the device comprising: a monitor for monitoring an operational characteristic of a light source comprised in the light fixture;
