Retail Bakery Display Case Lighting

Retail bakery display case lighting emits heat and damaging radiation from the UV and visible spectrums, increasing the risk of food borne illnesses from desserts containing eggs and dairy products and causing baked goods to become stale, fruit to wilt, chocolate to form a white film, colors to fade, and milkfats to become rancid.

Regular fluorescent lighting in retail bakery departments is skewed to emphasize the yellow and green wavelengths, which distorts the true colors of fruit, whipped cream, icing, and candy.

Promolux True Color Definition Lamps

Compared to other fluorescent lighting, Promolux Safe Spectrum 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. It is impossible to create a natural light that does not have any yellow or green wavelengths, so light sources will always be damaging to some extent.

However, since Promolux Safe Spectrum lamps minimize the emission of damaging visible spectrum and UV wavelengths, using Promolux lamps will prolong bakery shelf life by up to 50% and reduce shrinkage by 30% to 50% compared to the shrinkage caused by standard lights. These savings will vary depending upon the duration of light exposure, the type of packaging used, and the composition of the bakery product.

Choice of Lamp Color Temperature

Promolux lamps are available in two spectrum ranges: Promolux Safe Spectrum Gold lamps emit a warm tone perfect for giving breads, muffins, and donuts a just-baked appearance; while Promolux Safe Spectrum Platinum lamps emit a cooler tone which is ideal for accenting white colors.
