1878 – Thomas Edison, following work on a "multiplex telegraph" system and the phonograph, invents an improved incandescent light bulb. This was not the first electric light bulb but the first commercially practical incandescent light. In 1879 he produces a high-resistance lamp in a very high vacuum; the lamp lasts hundreds of hours. While ...

An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a filament that is heated until it glows. The filament is enclosed in a glass bulb that is either evacuated or filled with inert gas to protect the filament from oxidation .
The great advantage of the electric light bulb was the absence of flame and traces of combustion, thus avoiding all risks of intoxication, explosion or fire. In the beginning, the filament was made of carbonised vegetable fibres, then bamboo fibres and finally metal alloys until, in the early 20th century, the tungsten filament invented in 1904 ...
