Editing Halogen lamp (section)

===Specialized===
[[Projector|Projection]] lamps are used in [[Movie projector|motion-picture]] and [[slide projector]]s for homes and small office or school use. The compact size of the halogen lamp permits a reasonable size for portable projectors, although heat-absorbing filters must be placed between the lamp and the film to prevent melting. Halogen lamps are sometimes used for inspection lights and microscope stage illuminators. Halogen lamps were used for early flat-screen LCD [[backlight]]ing, but other types of lamps such as [[Fluorescent lamp|CCFL]] and now [[Light-emitting diode|LED]] are used.
Halogen lamps are used as the heating element in the fuser of many types of [[Laser printing|laser printers]]. The long tubular lamp heats the fuser roller from the inside, and the heat melts the toner onto the paper.
