Promolux True Color Definition Lamps at IFFA Booth #6.1.D 57

Promolux low UV merchandising lamps will be featured at the IFFA Meat trade show in Frankfurt, Germany May 5 – 11, 2007 in booth # 6.1 D57. 

Promolux now offers spectacular showcase and display lighting for meat display cases.  These lamps are designed to extend shelf life and increase sales through outstanding natural true color definition.
Heat sensitive products such as fresh meat can last as much as 50% longer due to the lack of dehydration, discoloration and fading. With Promolux lamps fresh meat is not cooked in the display cases due to the elimination of 86% of the harmful UV radiation rays usually found in regular fluorescent bulbs.  This leads to increased sales by creating more impulse shopping.
A high-tech retail lighting company is putting the bloom back into butchers fresh meat sales.
Using Promolux lamps means less rewraps, less discoloration, longer bloom on meat, and truer reds and whites in cuts. Its a sign of freshness rather than a tinge of yellow.  Meat and sausages exposed through traditional light sources usually show photo chemical reactions on the surfaces of the cut, company officials say. These lead to color changes: usually gray, thereby losing their fresh appearance.  Promolux lighting offers tremendous advantages to fresh meat managers including less product spoilage and an increase in customer eye appeal, which impacts directly on consumer impulse buying.

Ultraviolet radiation emitted from general purpose lamps encourages bacterial growth, enzymes, dehydration and oxidation, which break down product appearance. By using Promolux lights, retailers typically experience from one to three days extra shelf life.

Promolux lamps are specifically designed for specialized areas such as displays of perishable foods. They provide a perfect balance of color output to reveal the highest contrast for each and every shade of natural color that exists in various cuts of fresh meat and sausages. Promolux lamps are also approved in writing by health officials for applications such as meat display.

Today, consumers are demanding premium quality freshness, and if they don’t find it in your meat display cases, they’ll not purchase.

 Upgrading your lighting display cases to Promolux specialty lamps will save you money by increasing shelf life and by increasing consumer impulse purchases. Promolux an ideal investment because in many cases extended shelf life alone will pay for the bulbs in less than three months.  Promolux lamps are multi-coated with rare earth phosphors that are most often found in television picture tube coating. It is a more expensive coating process than used in making fluorescent lamps. Additional special coatings are used to control UV radiation and to protect the lamps from changing their faithful color reproduction.
 Wrapping fresh meat provides the opportunity to encase the meat in an atmosphere composed of a specific combination of gases, which allows retailers to control the timing of meat blooming and prolongs the storage life of the meat.  Modified atmospheres range from Controlled Atmosphere Packaging (CAP), which is 100% carbon dioxide and maintains the initial purple color of freshly slaughtered meat, to high oxygen Modified Atmosphere Packaging (MAP), which contains 70% oxygen and 30% carbon dioxide and is ideal for initiating meat blooming, the change in meat color from purple to bright red.
MAP with high oxygen concentrations helps to keep the red pigment stable within the muscle tissue for twice as long as meat exposed to air. In one study beef in high oxygen (70% oxygen and 30% carbon dioxide) modified atmosphere packaging remained fresh for four weeks at -1.5 C, and three weeks at 0C.
Promolux Safe Spectrum balanced full spectrum lamps emit lower levels of heat and ultraviolet radiation than regular supermarket fluorescent lamps, thus reducing the rate of meat decomposition. 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. 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, in a study conducted by the University of Zaragoza, meat that was displayed under Promolux low UV balanced spectrum lamps stayed nearly as fresh as meat kept in the dark, while meat that was displayed under regular fluorescent lighting quickly turned brown and began to decompose. Regular supermarket meat display case lighting shortens the brief period when meat is blooming, turning it brown prematurely; increases the rate of bacterial growth; and distorts the meats natural color.
