Editing Halogen (section)

=== Lighting ===
[[Halogen lamp]]s are a type of [[incandescent lamp]] using a [[tungsten]] filament in bulbs that have small amounts of a halogen, such as iodine or bromine added. This enables the production of lamps that are much smaller than non-halogen [[incandescent lightbulb]]s at the same [[watt]]age. The gas reduces the thinning of the filament and blackening of the inside of the bulb resulting in a bulb that has a much greater life. Halogen lamps glow at a higher temperature (2800 to 3400 [[kelvin]]) with a whiter colour than other incandescent bulbs. However, this requires bulbs to be manufactured from [[fused quartz]] rather than silica glass to reduce breakage.<ref name="Edison">{{cite web|title=The Halogen Lamp|url=http://www.edisontechcenter.org/halogen.html|website=Edison Tech Center|access-date=2014-09-05 }}</ref>
