Abstract: The mount is equipped with a lamp stand from which a first and second power supply line protrude such that they are parallel to one another, a first, short bracket being fixed to the first power supply line, and a second, long bracket, referred to below as a fixing bracket, being fixed to the second power supply line. The two brackets are arranged on a common plane, the two brackets being bent outwards away from the associated power supply line, and the two brackets being fixed to the associated power supply line of the stand such that they are offset with respect to one another.

Abstract: A metal halide lamp for general illumination purposes contains as the essential component of the metal halide fill manganese in an amount of from 0.01 to 50 &mgr;mol per cm3. It serves as a replacement for sodium at warm white or neutral white luminous colors.

Abstract: 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.
