Abstract
A metal halide lamp () includes a discharge vessel () which may be formed of a ceramic material. The vessel defines an interior space (). An ionizable fill is disposed in the interior space. The ionizable fill includes an inert gas and a halide component. The halide component includes a sodium halide, a cerium halide, at least one of a thallium halide and an indium halide, and optionally a cesium halide. The cerium halide is at least about 9 mol % of the halide component. At least one electrode () is positioned within the discharge vessel so as to energize the fill when an electric current is applied thereto.
