Abstract

A programmable luminaire system may comprise a programmable luminaire comprising an optic defining an optical chamber, a light source comprising a plurality of light-emitting elements, a controller operably coupled with the plurality of light-emitting elements, and an electrical connector electrically coupled with the controller. The system may further comprise a computerized device configured to electrically communicate with the programmable luminaire. The computerized device may be configured to transmit data to the programmable luminaire. The programmable luminaire may be configured to receive the data from the computerized device at the electrical connector. The controller may be configured to be programmed responsive to the data received by the controller.
