Canonical page: https://maeslighting.com/post/diamond-series-led-food-grade-lighting Technical article # Diamond Series Cold storage and food processing facilities require lighting that ensures both safety and hygiene while enduring extreme conditions. Maes Lighting proudly presents the Diamond Series NSF-Rated LED Lights, engineered to meet the demanding needs of these environments with superior performance. At [Maes Lighting](https://maeslighting.com/), we specialize in energy-efficient, durable LED solutions for industrial applications. This guide explores the features, applications, and benefits of the Diamond Series, showcasing why it’s the perfect choice for food-grade cold storage lighting. ## Understanding the Diamond Series NSF-Rated LED Lights The Diamond Series LED Lights are high bay fixtures designed for cold storage and food processing environments, where sanitation, temperature resilience, and reliable illumination are non-negotiable. These lights are built to exceed industry standards while providing exceptional brightness and efficiency. ### Features and Compliance Standards The Diamond Series is NSF-Rated for food-grade applications and IP69 Wet Location Rated, ensuring it withstands high-pressure washdowns and harsh cleaning agents. It’s rated for cold storage down to -40°C, outperforming standard lights typically rated for -20°C. Operating in a temperature range of -40°C to 45°C, the series is available in 150W (22,500 lumens) and 200W (30,000 lumens) models with a 120-degree beam angle for wide coverage. Its smooth, dust-resistant design and corrosion-free materials prevent contamination, making it ideal for hygienic environments. The fixtures are ETL and DLC rated, with standard chain mounting (pendant mount optional), a 5-foot cord, and no plug. ## Where the Diamond Series Shines: Key Applications The Diamond Series is crafted for industries requiring strict hygiene and temperature control, delivering reliable lighting in challenging settings. ### Food Processing and Preparation Areas In food processing plants, the Diamond Series ensures hygienic, bright illumination for tasks like food preparation, packaging, and quality inspections. Its NSF rating guarantees safety by preventing contamination risks during washdowns. For specialized tasks like meat processing, the high CRI (90) version of our [FY-HB Series](https://maeslighting.com/products/food-processing-lighting) complements the Diamond Series by ensuring accurate color rendering. ### Cold Storage Warehouses and Freezers Designed to operate at temperatures as low as -40°C, the Diamond Series is perfect for cold storage warehouses and walk-in freezers. It provides high-lumen output for clear visibility during inventory management or loading operations, ensuring safety in extreme cold. Combine it with our [vapor-tight LEDs](https://maeslighting.com/products/vapor-tight-lighting) for enhanced performance in humid or wet conditions. ### Harsh Industrial Settings The Diamond Series also excels in industrial environments exposed to moisture, dust, or extreme temperatures, such as beverage production facilities or pharmaceutical plants. Its robust design ensures consistent performance, supporting safety and operational efficiency in demanding conditions. ## Advantages of the Diamond Series LED Lights The Diamond Series offers significant benefits, making it a superior choice for cold storage and food-grade lighting compared to traditional options. ### Unparalleled Safety and Sanitation The NSF rating ensures the Diamond Series prevents contamination risks, such as glass breakage, in food processing areas. Its smooth, dust-resistant design and ability to withstand high-pressure washdowns maintain sanitary conditions. The [National Fire Protection Association](https://www.nfpa.org) underscores the importance of reliable lighting for safety in such environments. ### Energy Efficiency and Reduced Costs Delivering 22,500 lumens (150W) or 30,000 lumens (200W), the Diamond Series provides high brightness with minimal energy use, lowering utility bills. Its long lifespan reduces maintenance costs, particularly in hard-to-reach cold storage areas. The [U.S. Department of Energy](https://www.energy.gov) highlights LEDs’ efficiency in industrial settings. ### Robust Design for Extreme Conditions Constructed with corrosion-free materials, the Diamond Series endures harsh conditions like steam, moisture, and extreme temperatures. Backed by a manufacturer’s warranty, it offers long-term reliability, ensuring peace of mind in challenging environments. ## Why Maes Lighting Is the Go-To for Hygienic Lighting Since 2008, [Maes Lighting](https://maeslighting.com/), based in Broken Arrow, Oklahoma, has been a trusted provider of industrial LED lighting.
