Argon gas is used in fluorescent and incandescent light bulbs to stop the oxygen in the light bulbs from corroding the hot tungsten filament.The use of argon in light bulbs prevents the evaporation of the tungsten filaments, which results in increased light bulb life

Argon used in bulbs because the very thin filament inside the bulb would react with oxygen and burn away if the bulb were filled with air 8nstead of argon . Argon stops the filament burning away because it is unreactive .
