A light source is calibrated and operated. During calibration of the light source, calibration light is provided from a calibration light source. The calibration light is detected. A representation of the detected calibration light is stored. During operation of the light source, light is generated by the light source. The light generated by the light source is detected. The detected light generated by the light source is compared with the stored representation of the detected calibration light to generate information used to control color of the light generated by the light source.
