摘要：
PROBLEM TO BE SOLVED: To provide a lighting device prevented from lighting failure caused by a crack formed in a thin tube to leak a light tube, while a preferred color property is maintained.
SOLUTION: In the lighting control metal halide lamp having a pair of electrode 21 placed in the lamp, filled with a metal halide, provided with a lighting tube 5 having a surroundings 19 comprising a transparent ceramics, the metal halide comprises at least a kind of the rare earth metal halide consisting of dysprosium halide, holmium halide, thulium halide, holmium halide, cerium halide, and praseodymium halide, and sodium halide, together with at least a magnesium halide consisting of magnesium iodide and magnesium bromide, wherein the relations of A≥0.021p+0.313, and B≥10.0 in 0.0345A+0.0028B
