Abstract: Embodiments of the present disclosure generally relate to systems and methods for calibrating light-emitting diode (LED) light engines. The systems and methods described herein include characterizing the performance of a red-green-blue (RGB) LED light engine so as to enable the display of calibrated, dimensionless output values that accurately reflect a perceived brightness of illumination generated by the light engine for a specific output color.
