ABSTRACT:
A metal halide lamp of the present invention comprises a luminous tube alone without any outer bulb, the luminous tube containing metal halides such as neodymium halides (NdX.sub.3), dysprosium halides (DyX.sub.3) and cesium halides (CsX) in a total amount by mole of 1.times.10.sup.-6 to 8.times.10.sup.-6 mol/cc and the following molar ratios: ##EQU1## as well as rare gas serving as starting auxiliary gas and mercury serving as buffer gas. This structure permits a predetermined vapor pressure of the metal halides sealed in the luminous tube to be obtained without increasing the wall load, as well as the formation of a metal halide lamp having a long life and good color characteristics.
