Company: Fagerhult

Product: Concert LED lighting products

In the past, LEDs offered higher luminaries lumens per watt than comparable fluorescent solutions, but were too expensive compared with traditional products.

Only two years ago the relatively high cost per kilolumen of light output has been reduced to a point that now makes LEDs financially viable. As development continues, this cost will continue to reduce.

A typical retail application lit using Concert LED downlighters would usually be a combination of Compact Fluorescent downlighters, CDM accent spotlights and Tungsten Halogen accent downlighters. This would consume nearly 600W of electricity.

By replacing these with the equivalent Concert luminaries, the energy consumption is reduced to 350W. It is virtually maintenance free too, compared with traditional solutions that would require lamps to be replaced.

From a lighting quality point of view the Concert range brings warm colour temperature, excellent modelling characteristics and enhanced colour rendering to create a more comfortable environment.

In a recent project, namely Aldar Properties’ headquarters, the company used the new LED product Concert 500 for the toilets and reduced energy use and maintenance consumption by more than 20% just on those areas.

“We have achieved the same amount of savings in the open office areas with a 60x60 product.”

Recently, the company received client feedback on their quarterly electricity bill for 2009. “It has been proved that we stand by our word and the proposals we have made have been achieved. The energy bills have been reduced by 54% and the staff and children are happy and motivated in their environment,” the company said.

The cost-benefit dynamic is also starting to shift, the company adds. “All the different sectors keep in mind and try to follow the green design standards. Utilising the correct products with the latest design technology might cost a bit more initially, but the positive outcomes show within the first few years.”
