Running the Numbers for LED Lighting
Through a GATEWAY demonstration project, the Jordan Schnitzer Museum of Art showcased the impressive energy savings of LED lighting and complemented the contextual message of Chris Jordan's Running the Numbers exhibit. This composition depicted 320,000 light bulbs, equal to the number of kilowatt hours of electricity wasted in the United States every minute from inefficient residential electricity usage.

What does mass consumption look like? That was the provocative question behind an exhibit at the Jordan Schnitzer Museum of Art (JSMA) on the University of Oregon campus. In Chris Jordan: Running the Numbers, artist Chris Jordan depicted the staggering numbers of everyday products used at a national level and invited fresh thinking about ways to do more with less.
Thanks to the GATEWAY demonstration program, the audience for the exhibit got a good look at what savings can look like. The exhibit was lighted by Cree's LRP-38 product, substituting for the standard 90-watt halogen product otherwise used by the museum. The projected energy savings: over 75%.
The U.S. Department of Energy, Bonneville Power Administration, and Eugene Water and Electric Board were preparing to participate with JSMA on a GATEWAY demonstration of LED lighting elsewhere in the museum, when the museum determined that LED lighting and its associated potential for energy savings would be a perfect complement to the contextual message of the Chris Jordan exhibit.
Museum lighting is a "high-end" application with demanding requirements placed on the aesthetic aspects of the illumination, such as color rendering and color temperature, and appropriate beam intensity and spread. JSMA found this LED product to be more than adequate in all of these respects.
This location is part of a broader museum lighting effort undertaken by GATEWAY that involves LED installations at several museum institutions around the United States. The final report for the JSMA installation detailing energy savings, illumination comparisons, and cost-effectiveness of the LEDs is expected in summer 2011.
