Brookshire Brothers has launched a comprehensive lighting update involving in-store, parking lot, exterior signage and refrigerated case fixtures.
Using a combination of new linear fluorescent lighting and LED technologies — from GE Lighting, East Cleveland, Ohio — Brookshire Brothers will reduce its annual operating costs more than $235,000. The relamping has eliminated more than 3.8 million lbs. of CO2 emissions, with a reduction of 2.4 million kilowatt hours (kWhs) in electricity use.
“When we looked at options to impact our total energy costs, we identified several areas at different stores where new lighting, including LED fixtures, made a compelling case, both indoors and out,” said Eric Johnson, director of construction, Brookshire Brothers, Lufkin, Texas, which operates 72 supermarkets in Texas and Louisiana.
The fluorescent lighting retrofit, now completed chainwide, involved replacing 32-watt bulbs in approximately 450 four-lamp fixtures with GE’s more energy-efficient 28-watt T8 lamps. Existing ballasts were replaced with GE’s high-efficiency UltraMax electronic ballasts as needed. Each ballast installed will create additional energy savings of approximately eight watts per fixture.
The supermarket operator will save an average $3,200 per store annually in electricity expense with its new 28-watt solution, which represents a more than $220,000 annual cost benefit based on a $.09 kWh electricity rate and 12 hours use per day.
Brookshire Brothers is also utilizing LED technology. The chain replaced the fluorescent lighting in refrigerated display cases in four locations with GE’s Immersion RV40 LED lighting, designed to eliminate light-source glare and wasteful light spill typical of fluorescent-equipped displays. The LEDs will deliver a 60% energy reduction and are rated for 50,000-hours life, four times longer than the fluorescents they replaced.
“Our electrical contractor told me, ‘You wouldn’t believe how much of the work we do for you is to repair fluorescent door lighting.’ ” Johnson said. “In the stores that have been converted, everything is lit 100% of the time. That adds up to sales right there.”
Johnson plans to specify the
