Tungsten halogen is superior incandescent technology that offers 20% greater energy efficiency, longer service life and improved light quality as compared to standard incandescent technology. In a standard incandescent lamp the tungsten from the filament evaporates over time and is deposited on the walls of the bulb reducing light output. Also, the filament gets thinner and thinner and eventually breaks, causing the incandescent lamp to fail. Halogen gas inside a halogen lamp causes the evaporated tungsten to redeposit on the filament. This process slows down deterioration of the filament, improves lumen maintenance and extends the lamp’s service life. Read More.
Halogen lamps have higher color temperatures than standard incandescent lamps, being typically 3000k v. 2700k. With light output that contains more blue and green, Halogen lamps appear whiter and brighter too. Although standard incandescent and halogen both have a CRI of 100, the higher color temperature of halogen lamps actually provides more superior color rendition across a wider range of colors. Another benefit of Halogen is Halogen lamps can be extremely compact providing high lumen output with excellent beam control. For quality light and effective beam control Halogen works well. For more general lighting or higher efficacy, there are better choices.
