1. A solid state lighting device comprising:a body structure, a reprogrammable memory, at least one processor, a plurality of solid state light emitters, and a communication interface, wherein:
emissions generated by the solid state light emitters are arranged to be combined to produce aggregate emissions of the lighting device;
the memory is arranged to store a plurality of selectable algorithms each including different instructions for controlling operation of the plurality of solid state light emitters;
the at least one processor is in electrical communication with the memory and is arranged to execute steps of at least one algorithm of the plurality of selectable algorithms;
the communication interface is arranged to receive an additional algorithm including instructions for controlling operation of the plurality of solid state light emitters; and
the memory is arranged to store the additional algorithm received from the communication interface to permit the at least one processor to execute steps of the additional algorithm for controlling operation of the lighting device.
