Lubbock, Texas-based United Supermarkets recently retrofitted low- and medium-temperature refrigerated display cases in all of its 47 stores with a light-emitting diode (LED) product from GE Lumination, Valley View, Ohio. Lumination LED Refrigerated Display Lighting replaces United Supermarket's traditional T12 fluorescent lamps and T8 fluorescent lamps.
In all, United retrofitted more than 3,600 doors in its reach-in door merchandisers. United expects to save more than $633,000 annually in energy and maintenance savings ($369,000 in energy savings and $264,000 in maintenance savings).
