LAMP

There are many types of electrical lamps and in each one, electricity is used in slightly different ways to give us light.

In ordinary light bulbs, there is a filament through which runs an electric current, and when this glows, it produces light. If a filament is exposed to air, it will break in a moment that is why it is enclosed in a glass bulb in which there is a vacuum or gas which will not make it burn out.

This type of lamp gives out a warm light. There is also a filament in a halogen lamp, but the bulb is a little cylinder of quartz in which there are vapors of a halogen chemical.

This also gives a beautiful warm light. halogen lamps are often used for car headlights

Fluorescent lamps give out a whiter light, with gas flowing through a current.

This current stimulates the gas electrons which react by giving out light. the gases mostly used are neon, argon, sodium, and mercury.
