ABSTRACT:
A high intensity metal halide discharge lamp has a fill comprising mercury, sodium iodide and scandium triiodide plus an inert starting gas. Cadmium or zinc may be added in a molar ratio relative to ScI.sub.3 within the range of 0.04 to 1.0 to achieve a lowering in color temperature of several hundred degrees Kelvin at the cost of a minor decrease in lumens which is offset by an improvement in maintenance.
