Abstract
The invention relates to a high-pressure discharge lamp that has an electric power consumption of less than 50 watt and comprises a discharge vessel (1′) that is sealed on two sides and is made of a translucent ceramic material as well as electrodes (2′, 3′) which are disposed inside the discharge vessel (1′) and are used for generating a gas discharge. Xenon and metal halides are arranged within the discharge vessel (1′) which is embodied as a ceramic tube that has a uniform maximum inner diameter of 1.2 mm while the minimum cold filling pressure of the xenon amounts to 0.8 megapascal.
