Tungsten (W) or wolfram, doped frequently with thorium oxide.
Tungsten
Tungsten is an element. It is used in bulbs
Usually tungsten.
Tungsten is a common element found in cheap light bulbs as it is used to create the filament that gives off light when heated.
Tungsten is typically used as the filament in incandescent light bulbs because of its high melting point and ability to emit light efficiently when heated by an electric current.
Light bulbs contain a filament, typically made of tungsten, which produces light when electricity passes through it and heats up. This process causes the filament to emit light and illuminate the surroundings.
The metallic element in light bulbs is tungsten. Tungsten is used in the filament of incandescent light bulbs, as it has a high melting point and can withstand the high temperatures generated when electricity passes through it, producing light.
Filament of light bulbs are made up of Tungsten.

Tungsten is the most common element used as the filament in incandescent lightbulbs.
Incandescent light bulbs use a tungsten filament as the element that emits light when heated by an electric current.
Tungsten is commonly used as the filament in incandescent light bulbs because of its high melting point and durability.
