The invention relates to a gas discharge lamp, in particular a high-pressure discharge lamp for use in automobiles. The invention further relates to a lighting system with at least one light source, at least one light coupling system, at least one optical waveguide, and at least one light delivery system. Such lighting systems with a central light source and a distribution of the light over optical waveguides (i.e. suitable optical fiber systems) in remote locations are particularly suitable for applications in the automobile branch. For this application, a high brightness must be available already after a short run-up time of the lamp. To provide a gas discharge lamp with a high brightness, which makes available a sufficient brightness after a short period, a gas discharge lamp is proposed with a bulb which has an ellipsoidal discharge chamber in a central location, which chamber has a surface area with a maximum value of below 2.5 cm2, with two electrodes projecting into the discharge chamber which have an electrode interspacing Ea of 1.5 mm to 3.0 mm inside the discharge chamber, with a filling in the discharge chamber which is in a gas discharge state during operation of the lamp and has a filling density of 80 to 90 mg/cm3, with at least a mercury component in the filling which defines the filling density, and with an operating voltage between the electrodes in the discharge chamber of 80 to 90 V during lamp operation.
