    This property makes them among the very few simple, inexpensive sources available for generating such frequencies. For example, a standard 250-watt general-lighting mercury lamp produces significant output from 120 GHz to 6 THz. In addition, shorter wavelengths in the mid-infrared are emitted from the hot quartz arc-tube envelope.
