According to one aspect, a control system for an LED luminaire includes a dimming control circuit that develops an analog dimming command signal that is variable between zero volts and ten volts to command LED brightness. The control system further includes a modulation circuit coupled to the dimming control circuit. The modulation circuit modifies the analog dimming command signal so as to include digital data for further commanding a parameter of LED operation.
