A light-emitting diode (LED) is a semiconductor light source, which emits light when activated. LEDs are used as indicator lamps in many devices and are increasingly used for general lighting. LEDs have many advantages over incandescent light source including low energy consumption, longer life time, improved physical robustness, smaller size and fast switching. An LED is often small in area and integrated optical components may be used to shape its radiation pattern. The first visible-light LEDs were also of low intensity, and limited to red. Modern LEDs are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness. Early LEDs were often used as indicator lamps for electronic devices, replacing small incandescent bulbs.

Most fluorescent bulbs/tubes may not last more than 3-4 years (10000-15000 hrs of usage). But LEDs last much longer (upto 25000-50000 hrs of usage). All lights emit heat and the better the heat sink, the better the life. A good fluorescent light may last up to 4 years but can also die before that based on the environment and the quality of heat sink. Similarly life of LED will depend on the quality of its heat sink and the internal circuitry. Just like cheap CFLs, cheaper LEDs may not last long and thus buying a branded LED can be a better approach.
LEDs are always marketed as lighting options that give more brightness per watt of electricity. The claim is true if LEDs are used for spotlighting. LEDs are unidirectional source of light and thus they are excellent for spot lighting. LED that are available for general-purpose lighting have inbuilt reflectors that spread the light in all directions. And the use of reflectors causes decrease in brightness per watt. This results in their efficiency come down to as low as that of fluorescent lights. LEDs, or light-emitting diodes, are a form of solid-state lighting that is extremely efficient and long-lasting.
LEDs consist of small capsules or lenses in which tiny chips are placed on heat-conducting material. The small size and low profile of LEDs allow them to be used in spaces that are too small for other light bulbs. LEDs give off light in a specific direction, they are more efficient in application than incandescent and fluorescent bulbs, which waste energy by emitting light in all directions. The LEDs lights also light up instantly when turned on, does not flicker when dimmed and does not consume any power when turned off. They contain no glass components; they are not vulnerable to vibration or breakage like conventional bulbs. LED Lights does not contain any mercury which makes it safer for use and is not hazardous to health. The LED will provide energy saving benefit if it is used for spot lighting.
