Best Answer: The presence of inert gases like argon, neon or nitrogen inside the bulb retards the evaporation of the filament and makes it possible to operate it at higher temperatures than in vacuum. As the intensity of light from gas filled lamps is very high, they are in use for street lighting. The life span of an electric lamp is about 1000 hours. Any variation in the thickness of the filament reduces the life of the bulb considerably. Arc lamp or arc light is the general term for a class of lamps that produce light by an electric arc (also called a voltaic arc). The lamp consists of two electrodes, typically made of tungsten, which are separated by a gas.
