Premier Lighting Case Study: Fluorescent to LED Cooler Lights

Customer Profile:

County Line Liquor in Forest Lake, MN is a full service liquor store that has been a Premier Lighting customer for several years. In the past, Premier has retrofitted their T12 fluorescent fixtures to T8 lamps, and more recently installed LED BR30 lamps in their wine room. The latest lighting upgrade included replacing their T12 HO refrigerator lamps and fixtures with LED case lighting.


Refrigerator cases often have T12 lamps that are not energy efficient nor do they present the products as well as desired. Manager Michelle Murphy decided now was the time to upgrade the case lighting to LED to solve both issues.


The inefficent T12 lamps were to be taken out of the cooler doors and new GE LED cooler lights were set to be installed. Similar to how the T12 fluorescent lamps were using ballasts, GE’s LED refrigerator bulbs were powered by an external driver.


Before: T12 Case Lighting

After: New LED Cooler Lights


The improvement in lighting is quite obvious in the Before and After pictures above. Manager Michelle Murphy said, “It is like having new refrigerator case doors!” She also commented how easy it is to see the labels and packaging now. Further, County Line will have an estimated $1800 annual energy and maintenance savings, leading to a 74% ROI on the project. Xcel Energy rebates offset nearly 40% of the project cost.
