A metal halide lamp has a ceramic discharge vessel with two ends (5) which are closed off by sealing means which enclose a capillary tube (11). An electrically conductive lead-through (9) is passed in a vacuum-tight manner through a bore in the capillary tube (11). The capillary tube (11) comprises two sections (20, 21) which are arranged axially one behind the other, the diameter of the bore of the inner section amounting to at most 90% of the diameter of the bore in the outer section.

The lamp comprises a discharge vessel (2) which is closed off in a vacuum-tight manner and is arranged in an outer bulb (12), a getter material being held on a support body inside the outer bulb (12). The support body is a support strip (31) to which the getter material is applied, the support strip being bent in such a way that it is automatically held in the outer bulb (12) without the need for any auxiliary means.

According to the method the intensity of at least one pressure-independent (impurity detection) or pressure-dependent (gas pressure determination) spectral line is measured selectively. Indirect detection utilizes the intensity of spectral lines whose wavelengths correspond to higher levels of excitation energy than those of the impurities. The intensity of these spectral lines is a measure of the impurities. Alternatively, the intensity of at least one spectral line of the respective impurity is measured directly. In order to eliminate co-phasal interference, two spectral lines are measured and the ratio is formed therefrom. The intensity ratio of argon lines of wavelengths .lambda..sub.1 =772.4 nm and .lambda..sub.2 =738.4 nm has in particular proved acceptable for the indirect detection of impurities in argon and the intensity ratio V of the argon lines of wavelengths .lambda..sub.1 =763.5 nm and .lambda..sub.2 =738.4 nm has proved acceptable for determining the argon pressure. The measuring process is in particular suitable for integration in high-speed production lines for discharge lamps.
