    Abstract: Color-corrected high-pressure mercury-vapor lamp provides good color rendition of illuminated objects, and especially good color rendition of flesh tones. The lamp utilizes a particular phosphor coating principally comprising a two-component blend. One of the phosphor blend components provides an emission in the shorter wavelength region of the visible spectrum peaking at from 440 nm to 470 nm, and an example of this component is a strontium chlorophosphate having an apatite structure and activated by a divalent europium. The other phosphor component provides an emission in the longer wavelength region of the visible spectrum peaking at from 605 nm to 630 nm, and an example of this phosphor component is yttrium phosphate-vanadate activated by tervalent europium. For the foregoing examples, the relative weight ratio of the one phosphor component to the other phosphor component is from 0.05:1 to 0.4:1.
