Retail display case lighting applications

Food Service Retail Displays

The takeout market is a growing segment of the food service industry, involving foodservice professionals from restaurants and fast food outlets to supermarket food service departments. Turnover of merchandise can be very high especially for hot food displays, but this can be alleviated by using display case lighting that is safe for food and will extend the holding time or shelf life of the food.

REFRIGERATED HOME MEAL REPLACEMENTS IN SUPERMARKET SHOWCASES
UV and visible spectrum radiation from display lighting raises the surface temperature of home meal replacements even through refrigerated air, raising the risk of spoilage. Lamps that create visually appealing displays through true color rendering maximize impulse sales of HMR’s. <more...>

SALAD BARS
Foodservice display case lighting can have a damaging effect on salad bars, causing leafy green vegetables and fruit salads to wilt, and jello to become rubbery. If mixed salads, cottage cheese, and creamy salad dressings are heated by the radiation from display lamps, they can turn rancid or become unsafe to eat. <more...>

HOT FOOD BUFFETS IN RETAIL SHOWCASES
The holding time of hot food buffets can be shortened by display case lighting that radiates heat and radiation, which can cause hot buffet foods to dry out or become overcooked. Lighting that contains high proportions of the yellow wavelengths distorts the true colors of food, making unappealing displays. <more...>

DESSERTS IN REFRIGERATION SHOWCASES
Chocolates, cakes, and cream filled desserts are all sensitive to the harmful effects of display lighting commonly found in refrigeration showcases. Cakes become dehydrated, white films form on chocolate desserts, and creams develop off-flavors. <more...>

ICE CREAM SHOP COUNTERS
Under most types of lighting, ice cream develops off-flavors reminiscent of burnt feathers, cardboard, or metal. Radiation from lighting can also separate water from the ice cream and cause ice crystals to form. <more...>

Safe food lighting

Promolux True Color Definition Lamps

Promolux balanced spectrum lamps emit lower levels of heat and ultraviolet radiation than regular supermarket fluorescent lamps, prolonging the shelf life of foods. Compared to other fluorescent lighting, Promolux lamps emit 86% lower UV B radiation, a shorter wavelength that penetrates and causes heating, and 52% lower UV A radiation, a longer wavelength that tends to affect surfaces.

Because Promolux lamps are designed for true color definition, they have a more balanced visible spectrum than other fluorescent lamps. The yellow and green wavelengths that are predominant in regular fluorescent lighting are the most damaging wavelengths in the visible spectrum. Promolux lamps emit a more balanced range of wavelengths, including more of the red and blue wavelengths and more moderate levels of the yellow and green wavelengths, which results in greater sales through better eye appeal and increased consumer impulse shopping.
