Abstract: An improved discharge lamp is provided which includes a discharge vessel (arc tube) enclosing a discharge space, the discharge vessel (arc tube) including within the discharge space a metal halide ionizable material; first and second discharge electrode feedthroughs, and first and second current conductors connected to the first and second discharge electrode feedthroughs, respectively. The improvement is through the use of a field wire of a material that includes Ni or Ni alloy, and wherein the field wire material exhibits an electrical resistivity at 25null C. 4.0 eV; a thermionic emission work function>4.0 eV; and a melting point>1200null C.
