Abstract

The disclosure provides an LED light system that is easy to install and customizable by the user. The LED lighting system may be plugged directly into an existing power source. In one configuration, the system includes a power supply that accepts standard power inputs. A low voltage bus line extends from the power supply. The user may connect LED light modules at essentially any location along a low voltage bus line of the system so that the light modules are located exactly where the user desires light. Uneven spacing is possible. Different size lights, different lumen powers, and different-colored light modules may be disposed along the low voltage bus line. Security features may be used to reduce the value of the system components to a thief.
