Resources & Education: Commercial LED Lighting Guides

Back-Lit vs. Edge-Lit LED Panels: Evaluating Long-Term Color Consistency and Housing Depth

Edge-lit panels are ultra-thin but rely on an acrylic light guide plate (LGP) that can yellow or "tea stain" over time, causing a shift in Color Rendering Index (CRI). Back-lit panels are deeper (approx. 2") but place the LEDs directly behind the diffuser. Back-lit designs generally offer superior thermal management and more consistent color over the 50,000-hour rated life of the fixture.

Food Processing Lighting (NSF / IP69K): Why Standard Vapor Tight Fixtures Fail in High-Pressure Washdown Areas

Food-safe lighting requires NSF certification, which mandates a smooth, "no-catch" housing to prevent bacteria buildup. Standard vapor-tight fixtures fail in these environments because they cannot withstand the 1450 PSI spray used in sanitation. IP69K-rated fixtures are built with reinforced seals and non-toxic, impact-resistant lenses that will not shatter into the production line.

UFO High Bays vs. Linear High Bays: Determining the Right Optical Distribution for Open Floors and High-Aisle Racking

UFO high bays provide a circular light pattern best suited for open manufacturing floors and wide-area visibility. Linear high bays are designed for warehouse aisles, utilizing rectangular distributions that focus light onto the vertical faces of the racking. Using UFO fixtures in narrow aisles wastes 30-40% of the light output on the top of the pallets rather than the picking face.

IP65 vs. IP66 vs. IP69K: Decoding Waterproof Ratings for Industrial Washdown Lighting

IP ratings define the ingress protection against solids and liquids. IP65 is rated for low-pressure water spray, while IP66 is built for high-pressure "heavy seas" conditions. IP69K is the most rigorous industrial standard, specifically designed for high-temperature (80°C), high-pressure (1450 PSI) washdown in food processing facilities where standard vapor-tight seals would fail.

Wraparound vs. Strip Lights: Choosing the Right Low-Profile Fixture for Stairwells and Utility Corridors Under LPD Limits

Stairwell lighting is governed by strict Lighting Power Density (LPD) and occupancy sensing codes. Wraparound fixtures provide 180-degree diffusion to eliminate shadows in tight vertical spaces, whereas strip lights offer high-lumen, narrow-beam output for utility storage. For compliance with ASHRAE 90.1, specify fixtures with integrated ultrasonic or PIR sensors that provide bi-level dimming (10% to 100%) rather than simple on/off switching.

Retrofitting Surface Mount Wraparounds: Converting Legacy 4-Lamp T12 Fixtures to LED Without Repainting the Ceiling

The primary constraint in replacing 4-lamp T12 wraparounds is the "ceiling shadow"—the discoloration where the old housing protected the ceiling from UV and dirt. To avoid the cost of repainting, specify LED wraparounds that match the original legacy footprint (typically 9" or wider). Utilizing Type B ballast-bypass tubes or internal LED plate kits allows for a modern light engine while maintaining the existing mechanical footprint.
