Tungsten ( chemical name Wolfram ) is used for the filament of an incandescent lamp.
This is due to ability for making fine guage Tungsten wires , mechanical strength of such wires and the High melting point , which is considerably more than the normal operating temperature of the filament.
Generally, tungsten.

Modern light bulb filaments are usually Tungsten not Carbon. However early bulbs used things like silk coated with Carbon. Filament means thin thread. The bulbs are filled with inert gas like Argon to stop the filament from burning up with oxygen. Arc lamps use Carbon rods though.
Incandescent light bulbs need to have an inert gas or a vacuum to prevent the filament from being surrounded by air (with oxygen) which would enable the filament to catch fire and burn. Inert gases used include argon, krypton and nitrogen or some combination of them.
tungsten <<>> Also along with the above, aluminium for the shell, steel for the filament holders, and in past years brass was used for the shell until manufactures found out it was cheaper to use aluminium for the job.
No, not in the filament. You are probably thinking of compact fluorescent light bulbs, which do contain mercury.
Light bulb filaments are usually made of tungsten, which has a very high melting point. Occasionally carbon is used as a filament.
Domestic light bulbs are simply the light bulbs (usually of the filament type) used in the home.
Tungsten
Usually tungsten.
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.
Iron filaments are not used in light bulbs because they have a relatively high melting point and poor conductivity compared to tungsten, the metal commonly used in filament bulbs. Iron would not produce as much light or last as long as tungsten in a filament bulb.
Tungsten is an element. It is used in bulbs
Tungsten is the filament used in electric light bulbs that glows white hot when subjected to an electric current.

Generally, tungsten.
Argon is used in filament light bulbs to displace oxygen and prevent the filament from burning. It creates an inert atmosphere inside the bulb, helping to prolong the life of the filament and improve the overall efficiency of the bulb.
