The filament lasts for a long time because argon is inert and will not oxidize the filament even at high temperatures.
If air were used, the oxygen would quickly react with and destroy the hot filament within seconds of it being turned on.
Quick experiment: Attach a wire to the positive and negative sides of a large flashlight battery (the large rectangular ones with the two coils coming from the top... I can't think of the proper size). Attach the back of one alligator clip to the open end of each wire (so the clip part is not clipped on the wire). String out some steel wool until you have a single strand (or two or three wound together). This essentially is a light bulb filament. Clip it into the two alligator clips and watch how fast it burns.
An inert gas, like argon or nitrogen, is used in light bulbs to prevent the filament from reacting with oxygen and burning out quickly. By filling the bulb with an inert gas, the filament lasts longer and the bulb operates more efficiently.
The hot filament in an incandescent light bulb is protected by a glass bulb filled with an inert gas, such as argon or nitrogen. This gas prevents the filament from reacting with oxygen in the air, allowing it to glow and produce light.
Argon is used in a light bulb because it is an inert gas that helps prevent the evaporation of the tungsten filament. By creating an inert environment, argon helps increase the lifespan and efficiency of the light bulb.
Usually Argon or Nitrogen
yes argon is used for light bulb and it is not reactive
The gas typically present inside an incandescent light bulb is nitrogen or a mixture of nitrogen and argon. This gas helps prevent the tungsten filament from burning up by reducing the rate of evaporation.
The gas in a light bulb is Argon
nitrogen , and argon gas
The gas most commonly used in incandescent light bulbs is argon, which helps to prevent the filament from oxidizing and burning out too quickly. Other gases, such as nitrogen and krypton, may also be used in combination with argon to improve the efficiency and lifespan of the bulb.
Light bulbs are typically filled with an inert gas such as argon or nitrogen, along with a small amount of a halogen gas like bromine or iodine. These gases help to prevent the filament from degrading by reducing evaporation and oxidation.
argon - inert gas
The bulb has a filament made up of tungsten and a low pressure inert gas (argon, neon, nitrogen).
An inert gas, like argon or nitrogen, is used in light bulbs to prevent the filament from reacting with oxygen and burning out quickly. By filling the bulb with an inert gas, the filament lasts longer and the bulb operates more efficiently.

ARGON
No, light bulbs are typically filled with either a vacuum (no air) or an inert gas like argon. Nitrogen is not commonly used in light bulbs because it does not provide the same level of protection for the filament as argon.
An energy saving light bulb is simply a fluorescent light-bulb in a small housing with a built in starter . The gas used for it will be the same as a standard strip-light which is a tube filled with low pressure mercuric oxide and an inert gas like Argon Neon or krypton.
