As part of an energy efficiency project at the Upper Dauphin School District, GreenTech Energy Services retrofit the lights in the high school auditorium. In the main room, 150-watt metal halide high bays were retrofit with 30-watt LED high hats. In the back of the auditorium and a side room, fixtures with 100-watt incandescent lamps were re-lamped with 11-watt LED screw-ins. The new LEDs have enhanced the appearance of the auditorium – even the color of the seats seems brighter. They also improved light levels, significantly cut energy consumption, and eliminated obsolete technology that is costly to maintain.
