1. A spotlight for illuminating a film, studio, stage, event and/or theatre environment, comprising:
a light space having an optical axis which defines a light output direction;
a light source disposed movably in the light space;
a housing which delimits the light space and extends in the light output direction;
a main reflector which delimits the light space, extends transversely with respect to the light output direction and, relative to the light output direction, is disposed upstream of the light source;
an output optical unit which is disposed at a light exit side of the light space and, relative to the light output direction, is disposed downstream of the light source and outputs the light of the spotlight; and
an auxiliary reflector, wherein the auxiliary reflector is disposed movably, such that it can be positioned at least at a first position between the main reflector and the light source or at a second position between the light source and the output optical unit,
wherein the output optical unit can be reconfigured between a first configuration corresponding to the first position of the auxiliary reflector and a second configuration corresponding to the second position of the auxiliary reflector.
