Editing Halide (section)

==Uses==
[[:Category:Metal halides|Metal halides]] are used in [[high-intensity discharge lamp]]s called [[metal halide lamp]]s, such as those used in  modern [[street light]]s.  These are more [[Energy conversion efficiency|energy-efficient]] than [[mercury-vapor lamp]]s, and have much better [[colour rendition]] than [[orange (colour)|orange]] [[Sodium-vapor lamp|high-pressure sodium lamps]]. Metal halide lamps are also commonly used in [[greenhouse]]s or in rainy climates to supplement natural [[sunlight]].

[[Silver halide]]s are used in [[photographic film]]s and [[photographic paper|papers]]. When the film is [[photographic processing|developed]], the silver halides which have been exposed to light are reduced to metallic silver, forming an image.

Halides are also used in [[Flux_(metallurgy)|solder paste]], commonly as a Cl or Br equivalent.<ref name="indium">{{Cite web |url=http://www.indium.com/halogen-free/assets/PDF/Indium8_9HF_Overview.pdf |title=Halogen-Free Solder Paste |access-date=2011-03-21 |archive-url=https://web.archive.org/web/20120317004413/http://www.indium.com/halogen-free/assets/PDF/Indium8_9HF_Overview.pdf |archive-date=2012-03-17 |url-status=dead }}</ref>

Synthetic [[organic chemistry]] often incorporates halogens into [[organohalide]] compounds.
