2. The Challenge: Why Dairy The Challenge: Why Dairy Needs Special Lighting Needs Special Lighting Dairy products are very sensitive to heat and light. Standard “household” LEDs or supermarket lighting can trigger chemical reactions in milk, cheese, yogurt, etc. These reactions cause off-flavors, nutrient loss, and spoilage — impacting taste, nutrition and shelf Dairy products are very sensitive to heat and light. Standard “household” LEDs or supermarket lighting can trigger chemical reactions in milk, cheese, yogurt, etc. These reactions cause off-flavors, nutrient loss, and spoilage — impacting taste, nutrition and shelf life. life.

3. What Goes Wrong What Goes Wrong Under Poor Lighting Under Poor Lighting Exposure to harmful light + radiation leads to photo- and lipid-oxidation. In milk, this can cause fats to turn rancid, producing off-flavors described as “metallic,” “cardboardy,” or “painty.” Nutrients like Vitamin A, riboflavin (Vitamin B2), Vitamin D and others may degrade under such lighting. For clear-packaged cheeses / open-wrapped dairy items, light can also cause discoloration, color fading or moisture loss. Exposure to harmful light + radiation leads to photo- and lipid-oxidation.

4. Consequences for Retailers Consequences for Retailers and Consumers and Consumers Off-flavors and poor quality cause customers to avoid dairy products — hurts sales and trust. Shorter shelf life = more spoilage and waste; spoiled items may need to be discarded. Nutrient loss means dairy is less healthy — undermining consumer expectations of freshness/nutrition. Frequent markdowns or write-offs reduce retailer Off-flavors and poor quality cause customers to avoid dairy products — hurts sales and trust. Shorter shelf life = more spoilage and waste; spoiled items may need to be discarded. Nutrient loss means dairy is less healthy — undermining consumer expectations of freshness/nutrition. Frequent markdowns or write-offs reduce retailer profitability and increase shrinkage. profitability and increase shrinkage.

5. The Solution: Balanced-Spectrum The Solution: Balanced-Spectrum LED Lighting from Promolux LED Lighting from Promolux These lights minimize the wavelengths that trigger oxidation and nutrient loss. Provide stable, consistent illumination suited for refrigerated dairy display These lights minimize the wavelengths that trigger oxidation and nutrient loss. Provide stable, consistent illumination suited for refrigerated dairy display cases. cases. Balanced-spectrum LEDs (with “Safe Spectrum” technology) designed to emit lower levels of Balanced-spectrum LEDs (with “Safe Spectrum” technology) designed to emit lower levels of damaging radiation. damaging radiation.

6. Key Benefits for Dairy Key Benefits for Dairy Display Quality Display Quality Benefit What It Means for Dairy Displays Slows photo-oxidation and lipid-oxidation to keep milk, cheese, yogurt fresher longer. Longer Shelf Life & Freshness Helps retain vitamins (A, D, B2 etc.) and avoids off- flavors that repel customers. Preserved Flavor & Nutrition Maintains authentic colors of packaging and dairy products — more appealing to customers. True-to-Product Colors Cuts spoilage-related losses — some retailers see shrinkage drop by 30–50% after switching. Reduced Waste & Shrink

How It Works (Science Behind How It Works (Science Behind the Lighting) the Lighting) Conventional lighting triggers photochemical reactions when Conventional lighting triggers photochemical reactions when dairy fats and proteins are exposed to certain wavelengths + dairy fats and proteins are exposed to certain wavelengths + radiation. radiation. Balanced-spectrum LEDs emit a tailored range of wavelengths, reducing harmful radiation and limiting those reactions. Less heat and lower radiation exposure help maintain stable Balanced-spectrum LEDs emit a tailored range of wavelengths, reducing harmful radiation and limiting those reactions. Less heat and lower radiation exposure help maintain stable temperature and prevent quality degradation even in temperature and prevent quality degradation even in refrigerated cases. refrigerated cases.

8. Impact Across Dairy Impact Across Dairy Categories Categories Milk: Less off-flavor, better nutrient retention, longer shelf life. Cheese (packaged or open-wrapped): Reduced discoloration, less drying or moisture loss, preserved taste and visual appeal. Yogurt, butter, creams, other dairy-based items: Protection from oxidation helps maintain freshness, Milk: Less off-flavor, better nutrient retention, longer shelf life.
