A 0-10V dimmer is a robust, analog lighting control system that has become the standard for large-scale commercial and high-end residential applications. Unlike standard dimmers that control power on the main electrical line, 0-10V dimmers use a dedicated low-voltage signal to tell a fixture’s driver or ballast exactly what brightness level to produce. This method ensures perfectly synchronized, smooth, and reliable dimming across many light fixtures at once, making it the premier choice for professional lighting installations in offices, retail spaces, warehouses, and architectural projects.
How 0-10V Dimming Works
The principle behind 0-10V dimming is simple and effective. The system uses a pair of low-voltage control wires (typically purple and gray) that run from the dimmer switch to each compatible LED driver or fluorescent ballast. The dimmer sends a direct current (DC) voltage signal along these wires that varies between 0 and 10 volts.
- 10V Signal: The driver receives a 10V signal, commanding it to operate at 100% and deliver full brightness.
- 1V-9V Signal: As the voltage is reduced, the light output decreases in direct proportion. A 5V signal, for example, results in approximately 50% brightness.
- 0V Signal: At 1V, the light reaches its minimum dim level (often 10% or 1%). A 0V signal will either hold this minimum level or, in some drivers, turn the fixture off completely.
This direct, analog communication is highly reliable and less susceptible to the electrical interference that can cause flickering in other systems, ensuring consistent performance even over long wire runs.
