A LED light bulb is an electric light for use in light fixtures that produces light using light emitting.LED light have a lifespan and electrical efficiency which are several times greater than lamps and are significantly more efficient than most fluorescent lamp with some LED chips able to emit up to 303 lumens per watt .However, an LED lamp will never be as efficient as the LED chips it uses, due to losses from the LED driver that is required to use LEDs on mains voltage.
