The term LED stands for Light Emitting Diode and normally referred as Solid State Lighting. LED light bulbs are miniature bulbs that do not use filaments to produce light. Therefore, the life of an LED is much longer than that of a regular incandescent bulb, because there is no filament to burn out.

Incandescent tend to be much larger in size due to the filament, which must be housed in a vacuum inside the bulb. LED light bulbs last as long as a standard transistor used in modern electronics, and are lit purely by the movement of electrons.

The simplicity and long life of the LED make its use very desirable for various technological applications. LED light bulbs are housed in a durable plastic rather than glass and perhaps most importantly, are much more efficient.

In traditional incandescent bulbs heat is generated when activating the filament to produce light. This causes energy to be wasted on the production of heat rather than the production of light. In order to produce the same amount of light as an LED, an incandescent bulb would have to work even harder. LED light bulbs save electricity and lower electric bills.

In the past LED’s was commonly used for display applications such as, replacements for incandescent indicators, first used in expensive equipment such as laboratory and electronics test equipment, then later in such appliances as TVs, radios, telephones, calculators, and even watches. These LED’s were bright enough only for use as indicators, as the light output was not enough to illuminate an area.

With the advancement of White LED’s it is now possible to use LED’s in general lighting applications to replace Fluorescents and Incandescent.
