The lamp has a base element (2) connected with a wall or a ceiling such that the base element is secured against rotation relative to the wall or the ceiling. A light exit opening (6) is formed in a lamp head (4). A bearing unit (8) movably supports the lamp head against the base element. The bearing unit is designed such that the lamp head is rotatable relative to the base element around an axis (A). The lamp head is elongated and designed such that a longitudinal axis (S) of the lamp head and a normal (N) run parallel to each other.
