Bulbs

light bulb (also spelled lightbulb) is a device that produces light from electicity.In addition to lighting a dark space, they can be used to show an electronic device is on, to direct traffic, for heat, and many other purposes.

Early people used candles and oil lamps for light. Crude incandescent lights were made in the early and middle 19th century but had little use. Improved vacuum pumps and better materials made them shine longer and brighter late in the century. Electric power station brought electricity to urban and later rural areas to power them.Later gas discharge lights, including fluorescent lights, use less electricity to make more light.

Most lights fit into a socket. If the socket is turned on, there is electricity there, even if the bulb is out, so there is danger of electric shock. Most bulbs get very hot when they are turned on, and take some time to cool off. Most lights are made of glass, which means that they can break easily. Fluorescent bulbs contain a small amount of mercury, if they break, be careful to not breathe the mercury vapor. With all light bulbs , the filament will eventually break and the bulb will need to be replaced.
