Question

Why is the bulb filled with an inert gas/ nitrogen?​

Answer 1

Answer:

Filling a bulb with an inert gas such as argon or nitrogen 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.
