Abstract
A high intensity gaseous discharge lamp employs a discharge medium which emits radiation at multiple, narrow line wavelengths which combine to produce white light. Coatings are applied to the arc tube to prevent emission of certain ultraviolet and infrared wavelengths, and a cylindrical barrier blocks certain long wavelength infrared radiation from being emitted by the lamp.
