An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated to such a high temperature that it glows with visible light (incandescence).Over the first three-quarters of the 19th century, many experimenters worked with various combinations of platinum or iridium wires, carbon rods, and evacuated or semi-evacuated enclosures.Many of these devices were demonstrated and some were patented.

Most bulbs are used in a socket which provides mechanical support and electrical connections.

In 1840, British scientist Warren de la Rue enclosed a coiled platinum filament in a vacuum tube and passed an electric current through it.

The design was based on the concept that the high melting point of platinum would allow it to operate at high temperatures and that the evacuated chamber would contain fewer gas molecules to react with the platinum, improving its longevity.

In 1835, James Bowman Lindsay demonstrated a constant electric light at a public meeting in Dundee, Scotland.

He stated that he could "read a book at a distance of one and a half feet".
