Abstract
The invention provides a metal halide lampwherein the concentration of the filling components fulfill a condition according to claim. Such a lamp is found to be a good alternative to existing high-pressure discharge lamps (Ceramic Discharge Metal halide lamps) based on rare earth fillings or other metal halide fillings. In addition, such a lamp can be dimmed without a substantial shift of the color point. Such a lamp can also have photometric properties that are substantially independent of the arrangement of the lamp and/or the external temperature.
