Abstract: A high-pressure metal-vapor discharge lamp is formed by enclosing scandium-halide, preferably scandium-iodide (ScI3) in the amount of 1.80 X 10 7 to 9.27 X 10 6 gram mol/cc of confined gas, and at least 3.1 times said halide quantity in atomic ratio of free (metal) scandium, together with some mercury as a buffer gas, inside a translucent alumina tube. Such discharge lamp can maintain a luminous efficiency of over 70 lumen/Watt and a general color-rendering index of over 70 for a period in excess of 6,000 hours, and thus, it is very useful as a general lighting source.

Abstract: An electric discharge lamp having an excellent color rendition with a color acceptability higher than 1.0, a relatively high luminous efficacy and a good life performance, is provided, in a high pressure metal vapor lamp using a polycrystalline alumina ceramic tubing as the arc tube envelope within which sodium as a metal for producing radiant emission, mercury or cadmium as a buffer gas and xenon as a starting inert gas are contained, by controlling such quantities which are variable in the design of the high pressure metal vapor discharge lamp as the lamp wattage W in watts, an increased internal diameter of the arc tube envelope of the lamp d in millimeters, the interelectrode gap length L in millimeters and a lowered average potential gradient of the arc tube E in volts per centimeter in such a manner that they may satisfy the relations:
