Brookshire Brothers, headquartered in Lufkin, Texas, operates 72 retail supermarkets in an area covering Texas and Louisiana. Supporting its simple mission to “Create a satisfied customer!” the company recently launched a facility-wide lighting update including in-store, parking lot, exterior signage and refrigerated case fixtures.
Using a myriad of new linear fluorescent lighting (LFL) and LED technologies from GE Lighting, Brookshire Brothers has reduced annual operating costs more than $235,000 while establishing a model for energy-efficient lighting renovations at its stores.
As a part of the lighting upgrade project, re-lamping of linear fluorescent lighting (LFL) fixtures has been completed at 69 Brookshire Brothers locations where GE’s more energy-efficient 28-watt T8 has replaced 32-watt bulbs in approximately 450 four-lamp fixtures per 30,000-square-foot supermarket. These efforts include the replacement of existing ballasts with GE’s high-efficiency UltraMax® electronic ballast as needed.
Each UltraMax® ballast installed will create additional energy savings of approximately eight watts per fixture. Brookshire Brothers will save an average $3,200 per store per year in electricity expense after switching to GE’s 28-watt solution – a more than $220,000 annual cost benefit to the company based on a $0.09 kWh electricity rate and 12 hours use per day. The company plans to explore even more efficient 25-watt GE lamps and UltraStart® ballasts to suit future needs.
Another alternative product is the Aura long life fluorescent tube from Sweden, which is more efficient in this scenario. To achieve a much lower maintenance, we recommend the 32W Aura T8 Eco Saver tube to replace the existing 32W standard T8 tube. Not only can the end user benefit from the power loss of the standard T8 fluorescent kit, saving four wattages, it also can greatly reduce the maintenance costs because of its longer life time rating (50,000 ~ 63,000 hours), which is nearly one third higher than the GE tube.
Aura manufactures quality light sources and eco lighting solutions with at least three times longer lifetime and lower energy consumption than standard light sources. The mechanical, electrical and technical light specifications for Aura Super Long Life fluorescent lamps are comparable to conventional lamps, however the Aura design incorporates two patents that allow lamps to be rated up to 80,000 hours for T8 & 58,000 hours for T5 Types.
Using Aura long life lamps means:
In addition to standard triphosphor models Aura also produce lamps specifically for signage, cool rooms and hazardous area lighting.
The purchase price is just the beginning, when analyzing the real cost over time. Both maintenance, which may include the hiring of lifting equipment together with disposal costs should be considered.
The initial procurement costs can be easily identified, however other factors such as the inconvenience associated with electricians/ladders, the risk of accidents, and storage should also be considered.
