Abstract: A lighting control system for controlling a cumulative light emitted by a lighting fixture may comprise a light-emitting diode (LED) driver comprising an output for conducting an output current, and a control module electrically coupled to the output of the LED driver for receiving the output current. The LED driver may regulate the magnitude of the output current towards a target current, and may be characterized by a low-end intensity. The control module may be coupled to a first LED light source of the LED light sources. The control module may receive a command including a requested intensity and control the magnitude of a first LED current through the first LED light source. The control module may control the cumulative light output of the lighting fixture below the low-end intensity of the LED driver by diverting a portion of the output current away from the first LED light source.
