USE 1402.13 is a lighting system that can be installed by a licensed electrician. It can be used for multiple light configurations using OLS joiner (#1401). The system includes a universal mounting plate, back plates, plastic anchors, splice box cover, screws, and shade supports. It is important to make sure all power is turned off at the circuit breaker before installing the system. The back plates should be grounded using the center ground terminal. The system can be used with either compact fluorescent bulbs or incandescent bulbs.
