LED Refrigerated Display Case Lighting
Frozen food and refrigerated display cases in supermarkets are typically illuminated by fluorescent sources. Although they are reasonably efficient and reliable, fluorescent sources operate best at indoor temperatures of 60 to 80 degrees Fahrenheit. Light output for fluorescent lamps can drop by as much as 60 percent in cold temperatures. LED lighting, on the other hand, performs better as the temperature drops.
LED Display Case Lighting Benefits
Reduced Energy Costs
Higher energy efficiency and better performance at low temperatures allows LED case lighting to use up to 50 percent less energy than fluorescent systems. Additionally, LED systems emit less heat, which means the refrigeration compressor does not have to work as hard to remove heat as with fluorescent systems.
Improved Product Visibility
LED fixtures efficiently direct the light where it is truly needed, eliminating wasteful light that spills out onto the floor. LEDs are also able to illuminate shelves in a more uniform manner.
Reduced Maintenance Costs
A five-year warrantee and an estimated 50,000-hour useful life (significantly longer than fluorescents) can dramatically reduce costs associated with maintenance over the product lifetime.
Better for the Environment
Apart from energy savings and long life, LED lighting contains no mercury. Also, its reduced energy consumption will aid in preventing unnecessary green house gas emissions associated with energy production.
