Beschreibung
Zusammenfassung:	The invention relates to a lamp (10) and a vehicle headlight. The lamp (10) comprises a discharge vessel (16) with electrodes (20) arranged at a distance for creating an arc discharge. The envelope (22) has cylindrical shape with a cylinder wall extending straight in longitudinal direction. A reflective barrier (28) is arranged at least partly surrounding said discharge vessel for reflecting light emitted from the arc discharge. To obtain an optimally focused reflection, the discharge vessel (16) is configured such that the arc (50) is essentially straight. The reflective barrier (28) also extends straight in longitudinal direction.
