Abstract

A fixture configuration module comprises range control circuitry and fixture control circuitry. The range control circuitry is configured to store a range of a lighting parameter. The range identifies at least a subset of values of the lighting parameter supported by the light fixture to produce light. The fixture control circuitry is communicatively coupled to the range control circuitry and is configured to control the light fixture to produce the light in accordance with the range stored by the range control circuitry.
