Are you currently looking at buying a new bulb for several rooms in your home? If that's the case, I strongly recommend for you to purchase halogen bulbs rather than a normal electric bulb or a fluorescent bulb. Halogen light bulbs are a lot more efficient and they will last in the long run as opposed to traditional electric bulbs and fluorescent light bulbs. The low efficiency could be the problem that traditional electric bulbs face. Many of these light bulbs cannot last for over 1000 hours. The electricity consumed by these light bulbs is also high. Apart from consuming a relatively high amount of electricity, these light bulbs also have a tendency to heat up the room a lot.

Here follows a description of how a traditional electric bulb works... Argon or nitrogen are classified as the inert gas that electric bulbs are filled up with. A thin frosted glass envelop encloses the light bulb. The burning filament referred to as tungsten is normally present in the center of the bulb. The burning filament is made up of a tiny metallic wire made from tungsten. The metal tungsten is utilized here due to its high melting point - 2500 degree centigrade. Incandescence is the method in which an electric light bulb lights up. It takes place when the tungsten filament offers high resistance as a result of heat buildup when electric current passes through it.The resistance offered triggers the light bulb to glow. The key reason why these bulbs do not last long enough is because the tungsten filament tends to vaporize as a result of constant heat buildup. The continual heating leads to loss of tungsten filament.The quality of the light will decrease as the tungsten filament burns out thin. Just about all kinds of light bulbs function in a similar fashion with small differences in some places. The reason why electric bulbs are not preferred these days is because of their inefficiency. They are quite cheap to buy. But they have lots of challenges related to them such as... -

Within just 1000 hours of use they tend to fail- Excessive heat is generated near the bulb. It functions like a central heating facility.- The electricity used is much higherEven though Halogen bulbs make use of the same principles, they have a tendency to have a much higher effiency. Just like electric bulbs, halogen bulbs utilize a tungsten filament as well. Quartz glass is commonly used to enclose the tungsten filament of a halogen bulb. The quartz glass encloses the whole tungsten filament. As opposed to electric light bulbs which are generally filled up with non-reactive gases such as nitrogen and argon, halogen bulbs are filled up with a mixture of iodine and bromine gas (halogen atoms). When in contact with heat the halogen atoms reacts with the tungsten filament near the quartz surface. Upon cooling down, the tungsten atoms are recaptured by the filament. If quartz glass had not been used, the vaporized tungsten atoms might have been deposited at the glass surface and generated formation of a dark coating.
