A system and method for implementing an LED-based luminaire () incorporates one or more color channels (-). The luminaire includes a controller () that uses optical sensing and feedback to control LEDs (A) in each channel to deliver a consistent intensity and/or color output. The optical feedback loop may provide measured intensity and/or color of the luminaire's output to the luminaire controller. The controller may then adjust the current, pulse width modulation (PWM) duty cycle, or both, which are delivered to discrete color channels of the luminaire to obtain the desired intensity and/or color.
