Because if the thin filament wire was heated in regular air it would burn up.

What are energy efficient light bulbs made of?
A: There circuitry inside to boost the voltage to 300 500 volts and a triac to conduct the current but the bulbs as opposed to vacuum there is gas inside those coils.
How do they stop combustion occurring in light bulbs?
"They" do that by creating a vacuum inside the bulb (i.e., there's no oxygen in the bulb to burn).
Which gas is in electric bulb?
Modern bulbs are usually filled with a mixture of argon and nitrogen. More rarely, some bulbs are filled with pure argon, krypton or xenon. The earliest bulbs weren't filled with any gas, but had vacuum inside.

How do you produce light bulbs in CO2?
You do not. CO2 has nothing to do with the creation of a light bulb. A typical incandescent bulb has a vacuum inside. No light bulb uses CO2.
What would happen inside a light bulb if it was filled with air?
It would no longer work. Light bulbs are usually under vacuum and if air gets in the filament blows.
Why electric bulbs don't have air inside?
Electric bulbs do have the inert gasses inside and not oxygen to avoid explosions.
What is an element that is the gas in the light bulbs?
Argon or dry nitrogen are common fill gasses in high wattage bulbs. But low wattage bulbs are just vacuum with no fill.
What are the benefits of vacuum tubes and light bulbs?
They enable us to do things at night.
In a vacuum there's no what?
A vacuum is an empty space with nothing inside it.
Why cannot an electric bulb be repaired once damaged?
The gases (or vacuum) inside electric bulbs is usually specific to what kind of bulb it is. It can be repaired, by separating the glass from the metal, replacing/correcting whatever is broken, and resealing it in an environment that will have only that specific gas (or vacuum) inside. It can be repaired, but it's at least the same effort/expense (probably more) as making a new bulb.
What is the filoment?
Its the wire inside of light bulbs.
