The 120-volt Bar Light is designed for an easy installation with a hardwired or plug-in option. Open the front hatch for wiring or use the rear-access door for simple wiring access, then securely mount with two screws. Select between 3000K, 4000K, or 5000K for white light temperature, and then select between off/dim/bright for light output via switches on the fixture. Easily link additional units with a butt connector or linking cable
