Edison Light Bulb, 1879. Thomas Edison used this carbon-filament bulb in the first public demonstration of his most famous invention—the light bulb, the first practical electric incandescent lamp. The light bulb creates light when electrical current passes through the metal filament wire, heating it to a high temperature until it glows.
Electric lamps were first used only by a few but in time they got wider use and by 1885 it was estimated that around 300.000 lamps were sold only in USA. Electric lamps spread around the world and stayed until the present day in variety of uses, from home to industrial to street illumination.
The first successful test of the carbonized cotton filament was on October 22, 1879, which lasted 13.5 hours.
