The Kichler LED Driver + Dimmer simplifies installation and system compatibility by integrating the driver with the dimmer switch. This two-in-one product can convert 120V AC to 12V DC, as well as dim from 100% to 1%. Simply connect to both your high voltage input and low voltage output, and install with a standard single gang box to the wall to power Kichler 12V LED Tape and Accent Discs.
