In technical usage a replaceable component that produces light from electricity is called a lamp. Crude incandescent lights were made in the early and middle 19th century but had little use. In 1882 munich electrical exhibition in baveria germany cruto s lamp was more efficient than the edison s one and produced a better white light.

In addition to lighting a dark space they can be used to show an electronic device is on to direct traffic for heat and for many other purposes billions are in use some even in outer space. Thomas edison briefly pursued fluorescent lighting for its commercial potential. A light bulb produces light from electricity. He developed many devices in fields such as electric power generation mass communication sound recording and motion pictures.

Light bulbs with a carbon filament were first demonstrated by joseph swan in february 1879 and by edison in october 1879. He invented a fluorescent lamp in 1896 that used a coating of calcium tungstate as the fluorescing substance excited by x rays but although it received a patent in 1907 it was not put into production. Latimer received a patent on january 17 1882 for the process of manufacturing carbons an improved method for the production of carbon filaments for lightbulbs.

He is known as an independent early developer of a successful incandescent light bulb and is the person responsible for developing and supplying the first incandescent lights used to illuminate homes and public buildings including the savoy theatre london in 1881. An electric light is a device that produces visible light from electric current it is the most common form of artificial lighting and is essential to modern society providing interior lighting for buildings and exterior light for evening and nighttime activities.
