What is the gas inside a filament lamp?
Some light bulbs are filled with gas. The type of gas can vary depending on the type of light bulb. As the filament burns, tungsten particles separate from the filament, eventually causing the filament to weaken and break. The presence of gas inside the light bulb helps extend the lifespan of the light bulb by slowing the evaporation process of the tungsten.

Why do you need to have the glass on the outside of a light bulb?
The glass envelope, or bulb, of an incandescent light bulb is needed to hold the inert gas, such as argon, that fills the space. The filament of a light bulb is made of tungsten wire. When electricity passes through it the filament becomes extremely hot and emits light. The inert gas surrounding the filament protects it from evaporating too quickly. A light bulb only lasts as long as its filament lasts.
What is the difference between static electricity and the electircity in a light bulb?
