How to dim LED high bay lights?
In order to dim LED high bay lights, they need to come with a 0-10v dimmable driver. Typically, most fixtures include this as an optional feature right out of the box. However, since these fixtures require a control signal of low voltage in order to be dimmed, you will need to run two extra wires (usually gray and violet) from the switch box to the first fixture and each fixture in between for smooth dimming.
