Lights.com—Halogen Light Bulbs
Halogen light bulbs are one of the many different forms available to set an atmosphere in your home or office. Halogen bulbs use a tungsten filament to provide light. This filament is enclosed within a small quartz envelope compartment. Since the envelope is extremely close to the filament, it cannot be made of glass. If so, it would stand a high chance of melting.
Halogen light bulbs use a process that allows for a much longer life than offer bulbs. The filament inside the quartz envelope of these bulbs contains fluorine, chlorine, bromine, iodine or astatine. These gases help to provide the light that you see. In addition to this, these elements help to provide for a much longer life for the bulb.
The Operation of Halogen Light Bulbs
Halogen light bulbs recycle the very elements that produce light. The elements that combine with the tungsten filament at the correct temperature evaporate and then redeposit themselves on the filament. This allows for these light bulbs to last for a much longer period of time.
The major difference between a normal light bulb and that of a halogen bulb is the length of usage and the heat produced. Halogen bulbs reach extremely high temperatures. You should definitely be cautious when using these bulbs. However, they are great light producing bulbs that save money over time since they last longer.
