Function

• Halogen lighting uses a tungsten filament inside a gas-filled glass enclosure, along with a small amount of halogen. The halogen prevents the tungsten from evaporating, and continually regenerates the filament so it can be used again.
  
  

Benefits

• Halogen lights last longer than standard incandescent bulbs. The light produced is higher in the color spectrum, allowing even a small halogen bulb to illuminate a large area.
  
  

Types

• Halogen lighting is used to make automotive headlights, floodlights for public areas, residential light bulbs and stage lights.
  
  

Considerations

• Never touch the surface of a halogen bulb. Dirt or oil on the glass can cause a spot of focused heat that may melt the bulb or even lead to an explosion. Use rubbing alcohol to wipe the bulb clean if it does become smudged.
  
  

Warning

• Halogen lights generate extremely high temperatures and may create the risk of injury or fire. The ultraviolet light emitted can cause sunburns if the halogen bulb is not covered by a glass safety filter.
