LUBBOCK, Texas — United Supermarkets here has retrofitted low- and medium-temperature refrigerated display cases in all of its 47 stores with a light-emitting diode (LED) solution from Lumination, Cleveland, a GE Consumer & Industrial business. The LED solution replaces United Supermarket’s traditional fluorescent lamps. In all, United retrofitted more than 3,600 doors in its reach-in door merchandisers with the LED technology. United expects to save more than $633,000 annually in energy and maintenance costs, said Lumination. “Lowering our energy costs is very important to us,” said Michael Molina, vice president of facilities and design at United Supermarkets, in a statement. “The LED retrofit in our refrigerated coolers is providing significant energy savings.” The expected payback is 1.8 years through energy savings and many years of virtually maintenance-free service with a rated life of up to 50,000 hours, said Lumination.
