Thomas Edison demonstrated incandescent lighting to the public for the first time in 1879


 

On 31 December 1879, Thomas Edison demonstrated incandescent lighting to the public for the first time, in Menlo Park, New Jersey.

An incandescent lamp is an electric light with a wire filament heated until it glows. The filament is enclosed in a glass bulb with a vacuum or inert gas to protect the filament from oxidation. Current is supplied to the filament by terminals or wires embedded in the glass. A bulb socket provides mechanical support and electrical connections.
