5 5  0-10V dimming is one of the most common dimming methods for LED fixtures. It utilizes a 0-10VDC signal from the lighting controller to the fixture power supply or driver in order to control the brightness of the fixtures. This 0-10VDC signal is typically carried over a shielded pair of gray (negative) and violet (positive) wires. In the event that 0-10V dimming fixtures are exhibiting unexpected dimming behavior, an easy place to begin troubleshooting is at the lighting control module.

Constant current drivers dim the LED fixtures by varying the voltage output to reduce power while keeping current constant. Constant voltage drivers dim the LED fixtures by rapidly pulsing a constant voltage output. If the incorrect type of driver is used to power the fixtures (e.g. a constant current driver used for fixtures which require constant voltage), then the fixtures will not dim correctly. Verify that the drivers used are compatible with the fixtures.
