Retail Lighting Sparkle with LED
June 8, 2010
Traditional lighting using halogens, metal halides and even compact fluorescent globes cause high air-conditioning heat loads, continual globe replacement and high energy costs. In addition many retail outlets look the same. High intensity lighting is often sought to stand out from the crowd, making the problems above worse. Fortunately LED lighting offers the retail industry a win-win situation.
Solid state lighting or light emitting diodes LED has reached a maturity that addresses all of the problems associated with traditional lighting, plus no mercury waste disposal; a problem with compact fluorescent globes (CFL). That will receive more and more adverse publicity). To the retail lighting designer LED lighting offers more scope to brand an outlet and really make it stand out from the crowd, without resorting to high lumen intensity (now capped by the new building codes).
The nature of LED lighting requires a different approach to lighting design and not just allocating one globe per metre of retail space with a white colour. Incandescent globes and halogens only convert 5-10% of the energy used to light. The rest is heat. Count the number of halogens, normally 50W each, add a 20W each for the transformer, multiply by the kWhr rate and you’ll know the cost. Then add 20% of your air-conditioning costs (typical estimate) and you will have some idea of the cost of lighting.
LED lighting in contrast converts 95% of its energy to light. Its beam is highly directional; this attribute can be used to focus the light on merchandise you want to feature. The intensity of the light is achieved with low wattage, often between 10-27 watts. In contrast traditional lighting wastes light.
New Dimensions in Contemporary Lighting Design with Low Energy Technologies

Eco Living Centre’s Lighting Design Service combines innovative lighting design solutions with the latest in low energy lighting technologies including LEDs and induction lamps. Alistair Duncan, principal of Eco Living Centre says “modern lighting design employs the science of these environmentally friendly technologies and expresses them with the art of the aesthete. Good lighting design should add dynamism to a building and meet its functional requirements including health and safety.
