Supermarkets are discovering the benefits of LEDs:

  • LEDs cut energy use. Lighting costs are a major overhead for retail shops. Replacing metal halide, CFL, and halogen bulbs with LEDs can cut electricity bills by 50-80%.
  • LEDs can last for 50,000 hours. In a supermarket open 24 hours a day, LEDs can keep going for more than five-and-a-half years. This longevity means lower maintenance costs, and a reduction in disruptive bulb replacement.
  • LEDs do not emit harmful light. Traditional bulbs may spoil fresh food with infrared or ultraviolet light. LEDs emit neither of these. They help food stay fresh.
  • LEDs do not contain lead or mercury. LED bulbs are good for the environment. The energy efficiency of LEDs also reduces CO2 emissions and improves a supermarket’s carbon footprint.

The above points are strong arguments in favour of LEDs. They are certainly compelling enough to have convinced supermarkets around the world of the benefits of LEDs.

LEDs at the Migros Supermarket, Switzerland

In 2007, the Migros Supermarket in Switzerland changed its lighting system. LEDs replaced overhead, accent and refrigerator lights. The estimated saving in energy use was 80%.

LEDS and Morrisons

In the UK, the Morrisons supermarket chain is working with LEDs. The company has replaced the metal halide and fluorescent lighting at its Illingworth petrol station and convenience store. LEDs now provide the light for the illuminated signs, the petrol pumps and the car wash.

Spar’s multi-million pound LED project

Spar has started what is possibly the most far-reaching of the supermarket LED projects. After a successful pilot scheme at two supermarkets in Austria, Spar is engaging in a £44 million plan to introduce LEDs into its other stores.

Let’s hope it’s not too long before all the supermarkets embrace LED technology.  It will be better for the environment and for us – the shoppers.
