1. A light structure comprising:
a first housing having a light engine including at least one lighting scheme comprised of light emitting diodes (LEDs); and
a second housing for containing driver electronics for powering the light engine, the driver electronics including at least a mixing integrated circuit (IC) for controlling current to the at least one lighting schemes, and a near field communication (NFC) circuit having a near field communication (NFC) receiver and memory for storing instructions for sending pulse width modulation (PWM) signals from the NFC circuit to the mixing integrated circuit, the NFC receiver receiving an external command signal that the instructions stored in the memory of the NFC circuit employ to provide for an NFC control signal including at least one of the PWM signals to the mixing integrated circuit (IC).
