Abstract Supermarket freezers use interior case lighting to make products visible and to capture the attention of shoppers. For this publication, the Lighting Research Center evaluated a freezer case with prototype LED lighting side-by-side with a freezer case with standard T8 fluorescent lamps. Several LED conditions were tested, including full output and dimmed to approximately 80% output. Results from the study include energy use, product sales, and shoppers’ preference for each technology.
