Texas-based United Supermarkets LLC has retrofitted low- and medium-temperature refrigerated display cases in all of its 47 stores with a GE ecomagination product - an LED solution from GE Consumer & Industrial’s LED business Lumination LLC of Cleveland, OH, USA (formerly Gelcore).

The Lumination LED Refrigerated Display Lighting solution replaces United Supermarket’s traditional fluorescent lamps. United retrofitted more than 3600 doors in its reach-in door merchandisers. United expects to save more than $633,000 annually ($369,000 in energy and $264,000 in maintenance).

“The LED retrofit in our refrigerated coolers is providing significant energy savings,” says Michael Molina, United Supermarkets’ VP of facilities and design. 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. The LEDs also provide uniform color and up to three times the light-level uniformity of fluorescent lamps.

The GE LEDs can be turned off at night without any adverse effect on performance or lifetime, reducing the total hours of operation for the lighting in the refrigerated coolers from 24 hours per day with fluorescent lamps to just 16 hours per day.
