Quartz Radiant

These heaters use high temperature tungsten filament heating elements and operate at high temperatures. The element is encapsulated in a quartz tube and coated with a special material designed to maximise the output of infrared heat. The offer very high radiant efficiencies and have short heat-up and cool-down time -- typically one second to achieve 90% output. Quartz tubes are more fragile than ceramic elements, and have an operating lifetime of typically 5,000 hours. The high temperature of quartz heaters elements means that they produce visible light which, in some circumstances, can be considered obstrusive. The most common quartz lamps produce a ruby glow. Lamps are also available that produce a golden rather than ruby glow; these are often specified in situations where aesthetics are important, for example in places of worship.
