LED (Light Emitting Diode) is a semi-conductor chip that emits light(photons) when electric current is passed through it. LED technology, also known as Solid State Lighting (SSL) referring to the fact that light is produced from a solid object (semi-conductor) rather than in a vacuum or gas tube, is poised to revolutionize the way the world creates light. Recent advancements in LED have made this technology ready and available to replace outdated fluorescent, incandescent and neon. LED life span is over 100,000 hours.
