Safe Spectrum Lighting
SAFE DISPLAY CASE LIGHTING
Safe Spectrum, by Promolux Lighting International, represents the culmination of thirty-plus years of lighting design and research for the advancement of food-safe lighting for the food retail industry.
Years of research by renowned international food science laboratories, universities and dozens of field trials has lead to engineering of a food specific light source that is safe to use in all types of fresh food display cases.
Science and research have proven that foods break down at a chemical and cellular level when exposed to varying levels of radition both in the form of heat and light (visible and non-visible radiation).
4000K Spectrum
“Cool White”
Emphasis on Light Blue & Light Green
• Colors have no “pop” / dull
• This light drains color from everything
• Whites have slight blue over wash
3000K Spectrum
“Warm White”
Emphasis on Yellow
• Colors have yellow over wash / dull
• Makes red meat look very orangey-brown
• Whites have full yellow over wash
3500K Spectrum
Yellow/Orange
Emphasis on Yellow/Orange
• Colors have yellow over wash
• Makes red meat look orangey-brown
• Whites have full yellow tinge
Promolux Platinum
Balanced Spectrum
Filtering out yellow spectrum to protect fresh food, leaving small spikes in deep red and deep blue.*
• All colors are deep, saturated & vibrant
• Ideal for meat, seafood, produce, deli & floral
• Whites are clean, crisp & vivid
*This is not a “white” light LED. It’s a Balanced Spectrum LED where all colors “pop” and whites are crisp and vivid.
Food Safe Technology
PROMOLUX LEDS
The mindset that, “an LED is an LED is an LED” is one of the most critical mistakes made in the retail industry; the LED that’s in the ceiling should NEVER be used to merchandise the product you’re trying to sell!
LEDs, by nature, do not emit UVA or UVB radiation so it is often mistakenly assumed that they will not discolor or degrade perishable food. However, in real situations in supermarkets and grocery stores, LEDs continue to negatively affect fresh food.
There are portions of visible spectrum (between 500nm-630nm) that, when in close proximity to food, cause photochemical reactions leading to discoloration and degradation. And high power LEDs and LEDs with poor thermal management cause surface heating causing food to dehydrate and dry out.
Promolux eliminates those portions of visible spectrum known to damage fresh food, in most instances increasing shelf life 1-3 days. Promolux LEDs are designed using low power chip technology and superior thermal management making them the safest, most cost effective and sustainable LED for food merchandising and displays.
Years of research, development, and testing – and our dedication to understanding the impact that lighting has on specific foods, have made Promolux pioneers in the display lighting field. Promolux has learned from retailers, lighting specialists and food science specialists – and has turned that knowledge into the best merchandising LED available on the market today!
Increased Food Safety
Lower surface temperatures lead to reduced pathogen growth
Superior Merchandising
Balancing of the lamps spectrum provides unparalleled color presentation for retail food displays
Improved Shelf Life & Quality
Nutritional integrity, natural juices and moisture content and flavor are sustained
Promolux Chip on Board Technology (COB)
In 2009 Promolux began a partnership with major first tier chip manufacturers and packagers in order to achieve the highest quality and efficiency in LED lighting solutions. Chip On Board (COB) technology for linear LEDs, and now PAR LEDs is one of the most significant developments.
Chip on board directly mounts semiconductors on high quality printed circuit boards so that even in very small spaces, high packaging densities are achieved. The result is a powerful and long lasting LED.
Using COB solutions, Promolux LEDs achieve maximum power density and optimal thermal management – which is critically important when LEDs are in close proximity to fresh food and other perishable merchandise.
In addition to these benefits, Promolux’s COB technology reduces shadows and hot spots that are often seen on regular LEDS, and delivers more homogeneous illumination – maximizing the visual appearance of merchandise!
Prevent Food Surface Heating
Display lighting causes surface heating and promotes photochemical processes that contribute to discoloration, oxidation and food borne pathogen growth.
Perishable foods and merchandise that are sensitive to heat and light significantly benefit from being displayed under lights like Promolux, which incorporate Safe Spectrum science and technology. Designed to reduce levels of visible and invisible spectra Promolux is the safest, most cost-effective and sustainable lighting solution for food displays.
As pioneers in the field of food display lighting, Promolux Lighting International is pleased to present this educational portal on the science of food and food lighting. Here you will find years of scientific studies, research papers and industry reports on the impact lighting has on specific foods.
Whether you are a retailer, lighting specialist, university student or food science professional, we invite you to review the existing research and facts and encourage you to help build this site as an educational resource on the science of food and lighting.
Every wavelength of light is perceived as a spectral color and certain spectral wavelengths affect the chemical composition of foods.
