With their high efficiency, ultra-long life and their ability to reach full brightness instantly, LEDs are certainly the bulbs of the future. Here you can view some special offers, browse our full LED range, or learn a bit more about the technology behind Light Emitting Diodes...
LEDs use up to 90% less electricity than incandescent bulbs due to the fact that incandescent bulbs waste a lot of electricity through heat. LEDs are the most expensive technology however the benefits far outweigh the initial cost of the lamps.
LEDs are designed to last for between 25,000 hours and 40,000 hours, this is almost 2-3 times more than the best Compact fluorescent bulbs on the market today. LEDs have instant full light compared to the best energy saving bulbs on the market that you have to wait a while before you achieve full brightness. LEDs don't contain mercury and so you don't have to worry about health impacts upon the environment.

LEDs have been around for a while, dating back to the first practically useful visible LED invented by Nick Holonyak in 1962. Since then LEDs have come on leaps and bounds. LED light bulbs differ from standard incandescent bulbs by the way that they produce the light. An LED is what is called a 'solid-state lighting' technology, or SSL. Instead of emitting light from a vacuum (an incandescent bulb) or a gas (a CFL or fluorescent light), an SSL emits light from a piece of solid matter.
In the case of a traditional LED, that piece of matter is a semiconductor. Simply an LED produces light when electrons move around within its semiconductor structure. A semiconductor is made of a positively charged and a negatively charged component. The positive layer has "holes" -- openings for electrons; the negative layer has free electrons floating around in it. When an electric charge strikes the semiconductor, it activates the flow of electrons from the negative to the positive layer. Those excited electrons emit light as they flow into the positively charged holes.
