Halogen Lamps Is A Great Energy Saver

Author: MIKE SELVON

Nowadays, an increasing number of people are trying to find ways to maintain a good standard of lifestyle while also trying to be more "green" and responsible, with regard to being energy efficient in their homes. Light bulbs are in every home across the country, and because they are so prevalent, one great way to save energy and be "green" is to replace standard incandescent bulbs with halogen lamps, which use less electricity.

Halogen light bulbs provide more output for the amount of energy they consume, over other typically used bulbs. They are now used in homes, offices and even vehicles these days.



One of the reasons why halogen bulbs were originally developed was to address the issue of the short life span of typical incandescent bulbs. The development of the halogen type bulbs was very successful and nowadays the halogen lamps have a great reputation for being energy efficient in addition to having a very long life span. These factors have helped to make them a favorite option to standard bulbs.

Many times people refer to halogen bulbs as tungsten halogen light bulbs. This is because it is the interaction of the component of tungsten with the halogen that produces the brilliant light that is one of the hallmarks of halogen lighting fixtures. A halogen light bulb is made from a clear glass capsule that is filled with a halogen gas, such as iodine, along with a tungsten element and then it is sealed.

One of the interesting things that happen when a tungsten halogen bulb is lit is that minute pieces of the tungsten metal element will "evaporate" during the process of the light being produced. These tiny pieces of the metal are deposited within the capsule as hotspots and this factor actually helps to extend the life of the halogen lamp. This in turn means that halogen bulbs can operate at higher temperatures than incandescent bulbs, producing brighter light with the same amount of energy usage, making them more efficient.



During this chemical reaction that occurs in a halogen bulb the sealed capsule becomes extremely hot, which means that the typical type of glass used in other types of lighting fixtures cannot be used because it cannot withstand such intense temperatures. Instead of traditional glass, fused quartz is used to make the capsule for tungsten halogen light bulbs because it can stand up to the temperatures that are generated.

Halogen light bulbs are used in many different types of halogen lamps, including desk lamps, table lamps and floor lamps. They can be found in a wide variety of styles as well. Those who are looking for lighting fixtures that provide a lot of bright light, have a long life and use a relatively small amount of energy should definitely look at the options that they have for halogen lighting for their home or office.
