  "textContent": "A metal vapor discharge lamp whose near-infrared radiation is stronger than a conventional high-pressure discharge lamp, a projector utilizing this discharge lamp, and a metal vapor discharge lamp lighting device are disclosed. The metal vapor discharge lamp comprises a refractory light-transmitting hermetic vessel (1), a pair of electrode (3) fixed to the hermetic vessel (1), and a discharge medium sealed in the hermetic vessel (1) and containing a halide and a rare gas. Most of the light irradiated when the discharge lamp is in the ON state has near-infrared wavelengths (750 - 1100 nm).",
