Abstract

A plurality of LED light fixtures are mounted in a ceiling of an auditorium and a power control system is positioned in an area separate from a seating area of the auditorium for supplying power to the LED light fixtures. Each LED light fixture comprises an extrusion carrying one or more ambience light LED modules for providing ambient light and one or more high intensity LED modules for providing full level lighting. The power control system is configured to collectively switch the ambience light LED modules “on” and “off” and to separately and collectively switch the high intensity LED modules “on” and “off” to thereby provide either low level ambient light or high intensity full level lighting to the auditorium.
