Let’s look at the bigger picture – around 25% of all electricity in the UK is consumed through the use of lighting. Based on the fact that LED lights are much more energy efficient than alternatives (by up to 90%) – by switching to LED light bulbs the total electrical consumption can be reduced by a significant amount. The environmental benefits and scope are clearly huge! In addition – LED bulbs do not contain mercury or any other hazardous metals or chemicals that their CFL counterparts use.
