"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."
Talk about win-win! LEDs are cheaper to run, last longer, and give off a more natural light!
