A tungsten bulb is a common lightbulb, the fillamint in a bulb is the small wire in the middle that's drawn across the two contacts. This wire provides an electrical resistance and heats up and this generates light.
In a common lightbulb all the air must be taken out and replaced with an inert gas to stop the tungsten fillament burning away.
Halogen gas is in a Tungsten-Halogen Light Bulb.
The filament in an incandescent light bulb is typically made of tungsten. Tungsten is a metal with a high melting point that allows it to produce light and heat when an electric current passes through it.
Common old-fashioned light bulbs are of the incandescent type (including halogen) with a tungsten filament glowing at about 3000 degrees C emitting black-body radiation (light and heat). Tungsten is used because it has the highest melting-point of all metals. The other type of bulb is fluorescent, of various types like tubes and CFLs
The wire inside of an electrical light bulb is called a "filament". The word filament comes from the Latin word "filum" which means "thread". In various fields there are many different types of filaments with different uses, however the ones inside of light bulbs are made out of tungsten and work by super-heating by passing electricity through it.
It depends on the type of bulb. Tungsten is the most common element in light bulbs. But there are neon based bulbs also

What is Tungsten
The coating on the inside of an incandescent light bulb is typically made of tungsten or a tungsten compound. This coating helps to increase the lifespan of the bulb by preventing the tungsten filament from evaporating too quickly.
In the old style filament lightbulbs it was tungsten (wolfram).

Light bulb filaments.
I believe it is tungsten.
Tungsten is always in light bulb filaments :)
Usually tungsten.
The filament is the small coil that glows when the bulb is on. I believe its made out of tungsten
