- A type of dimmer control method that supplies a signal that ranges from zero to ten volts that, depending upon the voltage of the signal, tells a compatible ballast, driver or other similar device the level to which it should dim the bulbs it is powering.
- Dimming devices that accept signals 0-10V dimmers may not be compatible with all dimmers. Manufacturers of ballasts, drivers, transformers and also the dimmers themselves can provide upon request compatibility lists showing which combinations they have tested and found to be or found not to be compatible.
- 0-10V lighting controls and the devices they control always communicate using 2 separate wires, one that is solid gray colored and one that is solid purple. Note: some devices have purple and/or gray wires with white stripes in addition to solid gray and solid purple wires.
