Our LED Ceiling Panels include two driver covers on the back of the panel. One holds the wiring to power the light itself. That one should include a black wire (L), white wire (N), and green wire (ground). The other one includes wires to connect your compatible dimmer, if you want to add one. Dimmers are not included when you purchase the light.The Sunco LED Ceiling Light Panel fixture is dimmable via 0-10V dimming. Originally, 0-10V dimming was used as a standard means to control fluorescent dimming ballasts. You can use it on some drivers on LED lights, including this one.On LED lights, 0-10V dimming controls LED output intensity to change how much light is emitted.
