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
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.
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.
Yes, light in an incandescent bulb is a form of electromagnetic radiation, not matter. The light is produced by the heating of a tungsten filament in the bulb, causing it to emit visible light.
The coating inside a regular incandescent light bulb is made of tungsten. This coating is what emits light when an electric current passes through it, heating up the tungsten filament to produce light.

What is Tungsten
Tungsten is always in light bulb filaments :)
In the old style filament lightbulbs it was tungsten (wolfram).
The filament in a light bulb is typically made of tungsten.

Light bulb filaments.
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.
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.
Tungsten is the element commonly used to make light bulb filaments. Tungsten has a high melting point, allowing the filament to heat up and emit light efficiently without burning out.
