LED Light Bulb

An LED bulb is a solid-state lamp that uses light-emitting diodes (LEDs) as the source of light. LED bulbs are used for both general and special-purpose lighting.Compared to fluorescent bulbs LED bulbs contain no mercury, they turn on instantly, and the lifetime is unaffected by cycling on and off, so they are well suited for light fixtures where bulbs are often turned on and off. LED light bulbs are also less apt to break.
