Light Emitting Diodes (LEDs) are a highly energy efficient form of solid state lighting technology based on semiconductor diodes.
Increasingly popular in a wide range of applications, including domestic lighting, street lights, traffic lights, and consumer electronic devices, LEDs typically use a fraction of the energy required by conventional incandescent and fluorescent lights.
They also tend to offer a brighter light than other forms of energy efficient lighting such as CFLs and are widely regarded as a long term alternative to numerous existing lighting technologies.
