LED Light is a lamp with LEDs as the source of lighting

LED Light is a lamp with LEDs as the source of lighting. Our traditional or old lights  are incandescent  or fluorescent light bulb or tube. But now we can install the LEDs inside the lights fixtures, moreover the LED lights are more more efficient than incandescent or fluorescent bulbs.

So what's LEDs, actuall LEDs is very simply which  stands for light-emitting diode a semiconductor device that converts electricity to light by using the movement of electrons. LEDs were invented in Russia in the 1920s. They were put into practical use in the United States in the 1960s by General Electric. In the late 1960s, Monsanto Corporation was the first to mass-produce LEDs, and Hewlett-Packard used them in its early calculators.

Why do we need to use LED lights to replace  incandescent or fluorescent light bulbs. LED lighting consume much less energy. They are 300 percent more efficient than a compact fluorescent light (CFL), and 1,000 percent more efficient than an incandescent bulb. They have a very long life, about 50,000 hours of use at 70 percent of their original power. (LEDs don't burn out or flicker, they simply fade.) This works out to eight hours a day for 13 years at 70 percent power. A typical 60-watt incandescent bulb may last about 1,000 hours.
