Abstract

A light system that is controllable to generate a plurality of selected lighting effects, the light system includes a main processor, the main processor being in communication with a plurality of light sources; and each of the plurality of light sources having a distinct, known address whereby one of more of the light sources are individually addressable by the main processor, a known address being received by a selected light source of the plurality of light sources and acting to set the selected light source of the plurality of light sources in a disposition to receive a subsequent command from the main processor for generating a selected lighting effect. A light source and a method of forming a light system are further included.
