LED Lighting in a super Market

The Migros Supermarket in Eschenbach, Switzerland, sets an LED milestone by switching to 100% LED lighting throughout the entire store--in the refrigerated compartments, overhead, and accenting the selection of products on offer. This project demonstrates once again the ecological superiority of the LED technology. Migros expects to sink energy use 80%, including lower air conditioning costs due to the low waste heat generation of light emitting diodes. "How many Migros technicians does it take to change a light bulb?" None for the next 16 years! That's 50,000 hours of light, compared to 1,000 hours for an old-fashioned filament lightbulb. In addition to the waste reduction achieved by this long life-span, LEDs do not use harmful mercury nor lead. And there is one last, perhaps less obvious, advantage to LED lighting in a supermarket: LEDs emit no ultraviolet nor infrared light, minimizing spoilage of foodstuffs. According to the Osram case study: "Among light experts worldwide, the project is regarded as being unique, and blazes the trail into the LED future."
