To reach this temperature, the interior wall must be in close proximity to the tungsten filament.

T Big Benefits What Is a Halogen lamps offer a combination of benefits that make them an Halogen? appealing alternative to standard incandescents in many applications. Halogens are five non-metallic elements found in 7 of the . The term Brilliant, White Light: “halogen” means “ former” Halogen lamps deliver a crisp, white light. Not and compounds containing only is the quantity of the light greater than halogens are called “salts.” a standard incandescent of comparable The halogens are: (F), wattage, but the quality of the light creates (Cl), (Br), a higher contrast for reading and other tasks. (I) and (At). This also makes halogen perfect for display, accent and general . & Rendering: Since halogens are incandescent lamps, their CRI of 100 will render colors accurately and will match the color temperature of other light sources in the 3000K range. Long Life: Standard incandescent lamps and halogen lamps both use tungsten filaments. However, the filament in the standard lamp evaporates over time, causing it to weaken and eventually break. The gasses inside halogen lamps allow the evaporated tungsten to find its way back to the filament and redeposit, ensuring a long life of 2,000 hours or more. Lumen Maintenance: Compared to standard incandescent lamps, halogens offer superior lumen performance throughout the life of the lamp. HANDS OFF! Halogen lamps can be dimmed using a conventional incandescent . However, While conventional incandescent using a dimmer actually has an adverse effect on the lamps. lamps can be handled Standard incandescents benefit from being used with a dimmer due to the reduced voltage being applied to the filament. filaments need to be operated with bare hands, halogen at higher temperatures (250 degrees Celsius or higher) for the lamp to function properly. bulbs should not.
