A discharge lamp has a chemical fill in the discharge tube comprising an inert starting gas, mercury, alkali metal iodides, and a sufficient amount of scandium iodide and at least one iodide of a rare earth to increase the concentration of the rare earth in the vapor during lamp operation so as to enhance the color rendering index of the lamp to a value greater than about 80 and result in a color temperature between about 3000 to about 5000 degrees Kelvin.
