Halogen downlights use halogen incandescent bulbs, which are bulbs that have a small amount of halogen, such as iodine or bromine, in them. The halogen mixes with the tungsten filament to create a ‘halogen cycle’ which is a chemical reaction that helps extend the life of the light bulb. Halogen light bulbs are also capable of producing a brighter colour temperature, which makes halogen downlights ideal for rooms such as kitchens, where a brighter light is necessary to avoid cutting or burning oneself when cooking. As a safety note, it is important to ensure that halogen downlights are protected by a metal or glass cover, as they can be a fire hazard without one. Halogen downlight bulbs become hotter then normal incandescent light bulbs because the same amount of heat is concentrated on a smaller surface, and because the surface of the bulb is located closer to the heat-producing filament. Halogen downlights are often criticized for not being very energy efficient. We have other ranges of downlights on offer for the more energy conscious.
