Abstract : The new General Electric Lucalox lamp has been investigated as a possible far infrared source. The Lucalox lamp was compared with both a 100 watt and a 400 watt mercury arc and an Osram lamp in the spectral region from 50 to 350 wave numbers. The mercury lamps and arcs prove to be superior light sources in the far infrared. It also is shown that a nominal behavior following the Releigh-Jeans law is typical of both Osram lamps and mercury arcs in the far infrared. (Author)
