摘要： The invention relates to a metal halide lamp which is provided with a discharge vessel having a ceramic wall and enclosing a discharge space. Two electrodes having tips at a mutual distance EA are positioned in the discharge space, which contains besides Xe also an ionizable filling with NaI and CeI3. The discharge vessel has an internal diameter Di at least over the length EA. According to the invention it holds that Di ∫ 2 mm and also that the relation EA/Di ∫ 5 is complied with.
