Demonstration Assessment of LED Freezer Case Lighting

This report describes the process and results of a demonstration of solid-state lighting (SSL) technology combined with occupancy sensors in a set of upright grocery store freezer cases. The project was supported by the U.S. Department of Energy (DOE). A retrofit of freezer cases at a Eugene, OR Albertsons grocery store indicates a potentially successful application of light-emitting diode (LED) technology with additional energy savings from the use of occupancy sensors.
