Answer:

The main reason that bulbs are filled with an inert gas is to reduce evaporation of the filament and prevent its oxidation. The most popularly used filling in electric bulbs is a mixture of Argon and Nitrogen. ... Inside a bulb, this gas (mixture) is maintained at a pressure of about 0.7 atm or 70kPa.

Hint: Filling a bulb with an inert gas slows down the evaporation of the tungsten filament compared to operating it in a vacuum. This allows for greater temperatures and therefore greater efficacy with less reduction in filament life.
