What is 0-10V Dimming?

0-10V dimming started as a method for dimming fluorescents but is also used on LED lighting today. It’s typically used in offices, retail spaces, and homes with fixtures that have an LED driver designed for 0-10VDC dimming input. While it can be used for RGB or RGBW color-changing lights, there are some limitations. Each of the three or four colors needs to be assigned a zone so that the controller can adjust the intensity of each color separately to produce a range of color possibilities. If the color changing lights require additional inputs beyond intensity, a different dimming method should be used. For applications like entertainment spaces and those epic Christmas light displays that inspire “Ditto” lights from the neighbors, it’s common for people to use DMX512 protocol products instead, allowing them to connect the lights to a computer.
