Wal-Mart Stores, Inc., will outfit low- and medium-temperature refrigerated display cases in over 500 U.S. stores with a GE ecomagination-certified, light-emitting diode (LED) solution from GELcore, LLC, a GE Consumer & Industrial business (GE).
In stores where the new GE LED solution will be put to work, Wal-Mart expects to net up to 66 percent energy savings, compared with fluorescent technology. Wal-Mart will employ occupancy sensors and LED dimming capabilities to reduce the time the LED refrigerated display cases are at 100 percent light levels—moving from 24 to approximately 15 hours a day.
The combined environmental impact of a 500-store installation represents an annual 35-million pound reduction of carbon dioxide emissions. It also equals the good that comes from planting over 4,464 acres of trees or removing over 3,143 cars from the road for every year the LED lighting operates in place of fluorescent lighting. Wal-Mart estimates energy cost savings of a 500-store retrofit—one of the top energy-saving initiatives it will pursue in 2007—will exceed $2.6 million annually.
Wal-Mart reports that subsequent phases of the initiative will be aimed at retrofitting existing refrigerated display cases at many of its worldwide network of 6,689 stores.
GE engineers and technologists developed the company’s LED Refrigerated Display Lighting Solution over a period of years. The company worked closely with retailers and major refrigerated display case and refrigerated display case door manufacturers to design a solution that’s widely compatible for retrofit and new installations. Comprehensive and ongoing real world testing conducted by GE optimizes the levels of energy and maintenance savings that retailers will achieve.
Primary benefits of GE’s RoHS-compliant, UL-approved LED Refrigerated Display Lighting solution include: improved product visibility with reduced light-source glare on products and floors, hidden light source provides better access to products for stockers and consumers, more robust and better for the environment than fluorescent lamps because it doesn’t contain glass or mercury and it doesn’t produce UV or infrared light, up to 78 percent energy savings compared with VHO fluorescent lamps in a 5-door fixture, over two times the life of fluorescent lamps in a cold environment reduces maintenance costs and hassles (50,000 vs. 18,000 hours).
