halogen light bulb
A halogen light bulb is technically an incandescent light bulb. With a halogen light bulb light is emitted when a tungsten filament is heated. The difference between the two has to do with the composition of the glass envelope and the gas inside the envelope. An incandescent bulb has a heat sensitive glass envelope that contains an inert mixture of gases, and usually contains nitrogen-argon. When you heat the tungsten bulb, the filament evaporates and deposits metal on the cooler glass envelope.
It is amazing how the gases inside a bulb can affect its whole operation. Inside the halogen light bulb these gases combine with tungsten vapor and when the temperature is high enough the halogen gas will combine with tungsten atoms as they evaporate and redeposit them on the filament. Essentially this recycling process lets the filament last a lot longer.
With a halogen light bulb you will enjoy more light per unit of energy. Because the quartz envelope is so close to the filament it can be extremely hot compared to a normal light bulb. Save money and purchase all of your halogen lighting needs from an online merchant ready to serve you!
