Abstract
A light fixture including an array of LED light sources corresponding to a color channel of the light fixture, a driver circuit configured to drive the array of LED light sources, and a controller. The controller controls the operation of the light fixture to receive a direct drive signal related to a direct drive signal value for the array of LED light sources, determine an output of a reference light fixture based on the direct drive signal, determine a value for a color channel drive signal based on the output of the reference light fixture, and provide a control signal to the driver circuit to cause the driver circuit to apply the color channel drive signal having the value to the array of LED light sources. The value for the color channel drive signal results in an output of the light fixture that matches the output of the reference light fixture.
