How Are Halogen Light Bulbs Made?
Basics Many different types of light bulbs exist for different purposes. Halogen light bulbs are used in everything from cars to residual lighting, and are similar to ordinary light bulbs. A glass material encases a chamber in which a gas resides, such as argon or nitrogen. At the center is a tungsten filament that burns white hot when it completes an electrical circuit, causing it to emit light. Along with the light, the bulb generates a large amount of heat as well. Halogen lights are different from normal bulbs because the filament is encased in a smaller space, made of quartz instead of glass, since glass would melt due to the extreme heat involved. The gases, instead of being nitrogen or argon, are of the halogen variety. Base Materials The main material is the tungsten filament which lights up when an electrical circuit is completed. This material can withstand temperatures of up to 4,500 degrees F. The connecting wires are usually made of nickel and iron. Glass forms the bulb it
