Abstract

The invention is a discharge lamp comprising a halogen selected from the group consisting of fluorine F, chlorine Cl, bromine Br, and iodine I; a transitional metal selected from Group IVB, VB, VIB or VIIB of the periodic table, and sulfur. The presence of the sulfur in the lamp causes an increase in the radiation emitted in the green and/or red radiation bands, thereby improving the spread of colors emitted by such a lamp. This effect is believed to be due to the presence of sulfides of the transitional metal selected from Group IVB, VB, VIB or VIIB in the discharge space. This effect may be utilized in both low- pressure and high-pressure operating modes.
