Beginning with its first store in 1936, Stater Bros. in San Bernardino, Calif., has a long history of doing right by its customers and the environment. An LED lighting upgrade was among the supermarket chain's efforts to adopt environmentally sensitive practices, along with solid waste landfill diversion, daylight harvesting with skylights, and the use of high-efficiency motors in heating and cooling systems.
Stater Bros. met with strategic sourcing partner TopSource, LLC (Quincy, Mass.) to pursue energy-efficient opportunities in its lighting portfolio. After evaluating lighting options from five different manufacturers, Stater Bros.' retail marketing team chose GE's refrigerated display lighting to replace the 60-watt fluorescent fixtures in freezer cases.
GE's Immersion™ RV40 LED lighting system was selected to replace fluorescent lights in the frozen-food cases at nearly all of the retailer's 166 grocery stores. With installation crews completing 20 Stater Bros. stores per week, all 15,000 freezer doors were retrofitted in about 10 weeks.
Results & Benefits
The switch to GE's energy-saving Immersion RV40 LED lighting system helps retailers like Stater Bros. slash the operating cost of refrigerated displays while enhancing the visual appeal of vertical cases.
By replacing 60-watt fluorescent lamps with GE's 16-watt LED lighting, Stater Bros. will use 28,444 fewer kilowatt hours (kWh) per store per year, a savings of approximately 4.6 million kWh across the 163 participating stores and equating to about $510,000 in annual savings (based on an $0.11 kWh rate and 17 hours of operation a day).
The long-life Immersion RV40 LED lighting system also contributes to an 80 percent reduction in maintenance costs—totaling nearly $60,000 in savings annually across all locations for Stater Bros. As an extra benefit, LED lighting generates less heat, which translates to fewer compressor cycles in the food cases for additional indirect energy savings.
“We've received great feedback from customers and store managers,” said Scott Limbacher, vice president, Construction/Maintenance at Stater Bros. “Our managers tell us the new lighting really makes their products pop.”
