Abstract
An illuminated refrigerated display cabinet having a refrigerated product compartment includes a door frame defining an integrated raceway extending along a horizontal upper portion of the door frame. Electrical ballast associated with florescent tubes are mounted in a raceway chamber of the raceway and are accessible through a movable raceway chamber access door. The raceway chamber can be accessed without opening doors accessing the refrigerated product compartment thereby eliminating cold air losses, increasing efficiency and lowering operating costs.
