Editing Phosphor (section)

===Lighting===
Phosphor layers provide most of the light produced by [[fluorescent lamp]]s, and are also used to improve the balance of light produced by [[metal halide lamp]]s.  Various [[neon sign]]s use phosphor layers to produce different colors of light. [[Electroluminescent display]]s found, for example, in aircraft instrument panels, use a phosphor layer to produce glare-free illumination or as numeric and graphic display devices. Most white [[LED]] lamps consist of a blue or ultra-violet emitter with a phosphor coating that emits at longer wavelengths, giving a full spectrum of visible light. Unfocused and undeflected [[cathode-ray tube]]s have been used as [[Strobe light|stroboscope lamps]] since 1958.<ref>{{cite web |url=http://www.mif.pg.gda.pl/homepages/frank/sheets/074/c/CL60.pdf |publisher=[[Ferranti]], Ltd. |title=''Vacuum light sources — High speed stroboscopic light sources'' data sheet |date=August 1958 |access-date=7 May 2017 |url-status=live |archive-url=https://web.archive.org/web/20160920125303/http://www.mif.pg.gda.pl/homepages/frank/sheets/074/c/CL60.pdf |archive-date=20 September 2016 }}</ref>
