Halogen Lights are similar to incandescent lights but have numerous differences. For one they last longer.They are also more energy efficient Along with these qualities you will find that they are also more expensive. Halogen Light bulbs contain an inert gas (such as Argon or Nitron) and a Halogen gas (such as Bromine or Iodine). These are located inside a small envelope along with a small filamentof tungsten. Tungsten is a hard, gray, metallic element that is extracted from certain minerals. It has one of the highest melting points of all of the metals. Due to its high melting point, it is ideal for use in a high temperature enviroment. When the bulb is turned on, it causes the mixture of the tungsten filament to evaporate. These atoms than react with the Halogen gas enclosed in the bulb. Once they react they return to the tungsten bottom and seemingly recycle. This is what allows the light to last so much longer. Also, partially due to the igh melting point of tungsten, the filament is heated to a great degree which produces more light for the given amount of energy used. However, since it is heated to such a great extent, it can be very dangerous and also flammable since it is so hot. |
