A field trial of LED light fittings in social housing says the new technology can deliver huge energy savings, reduce costs and makes residents feel safer.

The study, carried out by the Energy Saving Trust (EST), measured the performance of more than 4,250 LED light fittings installed at 35 sites.

The EST said it carried out the trial because an increasing number of LED lights were now commercially available.

It is predicted the technology could dominate the lighting market by 2015.

“We like to test things in-situ in order to understand their real performance rather than rely on manufacturers’ claims,” explained James Russill, EST’s technical development manager.

But, he added: “We are at one of those rare times when there is a revolution, I think it is fair to say, within the lighting sector.

“LEDs promise to be the way forward for the whole sector, to be honest. There are so many benefits: they can be smaller, brighter; it is one of those rare technologies where the trial has shown it performs better than the lighting systems it is replacing but, at the same time, using less energy.” …

Light-emitting diodes have been around for years.

Traditionally, they have been used as indicators on electrical devices, such as standby lights on TVs. This was because LEDs were only available in red, but recent advances means that other colours are now available, and the light emitted is much brighter.

White light (used for general lighting) using LEDs can be created via a number of techniques. One example is mixing red, green and blue LEDs.

It is suggested that LEDs can last for up to 100,000 hours, compared with the 1,000 hours of traditional incandescent light-bulbs and compact fluorescent lamps’ (CFLs) 15,000 hours.

The technology is also much more energy efficient, using up to 90% less energy than incandescent bulbs.

The long lifespans and low energy use make LEDs economically attractive because even though the fittings cost more, the running and maintenance bills are lower. …

Great, we will all have fewer wrinkles. ;-)
