Halogen bulbs are actually an advanced variation of incandescent bulb technology. One of the major factors that shorten an incandescent bulb's lifespan is the evaporation of the tungsten within the bulb. By adding a trace amount of a halogen gas (methyl bromide) inside the bulb, a chemical reaction removes the tungsten from the wall of the glass and deposits it back onto the filament, extending the life of the bulb. The higher temperatures of halogen lighting contribute to a whiter light, a higher light output and a greater efficiency.
When it comes to energy savings, halogen lighting is the smart choice. Halogen not only offers the highest Color Rendering Index (CRI) to provide crisp, white light and a pleasant tone, but also provides a cost-efficient alternative to incandescent bulbs. These bulbs are available in a wide range of sizes and lumen packages to fit a variety of lighting applications.
