These are an emerging technology and are expected to be the future of household lighting. LED bulbs suited to standard fittings are increasing in variety and more options are expected to be available in the next couple of years. LEDs are more expensive to buy but have a life expectancy of up to 50,000 hours (that’s 50 years for the average household light!) and can use up to 88% less energy than the standard incandescent.
As LEDs evolve, bulb costs are decreasing and they are now available in ‘warm white’ (the best light colour for home use), have a good light spread and are dimmable.
There are now LED lights that are the same size and shape as traditional incandescent or halogen bulbs, and use even less energy than CFLs. These LEDs can fit into conventional fittings.
