A refrigerated display case and process of illuminating the case is provided. The display case has a support mullion (22) positioned in proximity to a glass door. A fluorescent lamp (34) is located within a lateral opening along either side of the support mullion (22). A diffusing lens (32) is positioned within the lateral opening, opposite the lamps, scattering the light as it passes through from the side of the mullion and through the diffusing lens (32). The glass door provides a reflective surface which reflects a substantial portion of the scattered light towards the interior space of the display case.
