LED cooler lights are installed in chillers, freezers, refrigerated cabinets and shelves to enhance product visibility and attractiveness. In retail stores, how the product is visually communicated to customers has a great influence on their decision to make a purchase. Refrigerated displays require specialized lighting to efficiently, effectively and safely enhance the appeal of merchandise. Conventional fluorescent lighting fixtures have a reduced lumen output at minus 20° Celsius, which compounds the operational inefficiency pf these fixtures. Fluorescent lights generate heat, which accelerates food deterioration and promotes microbial growth.

LED lighting offers so much more than just improved luminous efficiency, it has dramatically changed the landscape of refrigerated display lighting. LEDs do not radiate infrared (IR) and ultraviolet (UV) energy. This addressed challenges confronted by legacy technologies, leading to minimum food deterioration over expected shelf life extension.

Another feature that contributes to the technology’s supremacy over fluorescent lighting is that LEDs can be spectrally optimized to enhance the color of the displayed merchandise. The spectral power distribution (SPD) of a light source determines how object colors are rendered. The spectrum of LED cooler lights can be tailored in exact proportions to provide the product-specific color rendition and the most appropriate correlated color temperature for the enhanced look of the displayed merchandise.

At sub-zero temperatures, LEDs operate more efficiently and last longer than they do at ambient temperatures. The miniature design of LED cooler lights allows attention to be focused on the displayed products while the light fixtures remain neatly out of sight. LED cooler lights are usually linear LED fixtures sealed for moisture resistance.
