Quartz lamp
Revision as of 06:13, 24 July 2013 by (username removed)
Description
1) An incandescent lamp that uses a quartz bulb, rather than glass. Quartz bulbs generally use a tungsten filament but run at a higher color temperature than glass bulbs. Thus they have very good color rendering properties. Quartz bulbs are often used for photography. Tungsten-halogen bulbs are quartz lights that contain a small amount of iodine which extends the life of the bulb. Quartz transmits the ultraviolet radiation well and thus emits greater UV light than glass bulbs.
2) A lamp that contains an ultraviolet light source, such as mercury vapor, enclosed in a fused quartz bulb. See mercury vapor lamp.
