The first electric light bulb, invented by Thomas Edison, had carbonized thread as its filament, and burned for 45 hours. Edison experimented with many other filaments, including red hair and a mixture of lamp black and tar.

Incandescent filament lamp, first demonstrated by Joseph Swan in the UK in 1878 and Thomas Edison in the USA in 1879. The present-day light bulb is a thin glass bulb filled with an inert mixture of nitrogen and argon gas. It contains a filament made of fine tungsten wire. When electricity is passed through the wire, it glows white hot, producing light.
