LEDs, or light-emitting diodes, are becoming more popular with electronics and lighting alike. Until recently, LEDs were not available for lighting but the technology may become the most popular form sold in lighting, surpassing both incandescent and compact fluorescents.
LEDs are currently not as popular as the aforementioned due to the cost. However, LEDs use ninety percent less energy than the common incandescent light bulbs. In addition, LEDs have been found to have a lifetime of upwards of 100,000 hours. This is compared to 1,000 hours for an incandescent and upwards of 15,000 for compact fluorescents. The benefits of LEDs may make them top in lighting within a few years according to a new study.
The Energy Saving Trust (EST) recently conducted a study of LED lighting at thirty-five locations for social housing. A total of more than 4,250 LED lights were installed for the study. The goal of the study was to test the overall performance of the LEDs in addition to acquiring opinion on the use of the lighting.
Overall, the study found that the LED lighting not only reduced energy use and saved customers money, but many residents of the social housing where they were installed preferred them to regular lighting based on appearance. Residents felt the lighting appeared more light daylight than typical lighting and made areas feel safer due to the brightness and reach of the light.
In terms of energy savings, the thirty-five sites will reduce energy use in one year by three million kilowatt hours because of the change to LEDs. Those conducting the study believe that LEDs will likely be the top lighting of choice by the year 2015.
James Russill, the technical development manager of EST, stated: “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.”
