Claim 0:
1. A lighting system comprising a first light source, a second light source, and a control system, wherein:
the first light source is configured to generate first light source light with a controllable first radiant flux, wherein the first radiant flux is dimmable over a first dimming range;, wherein the first light source light has a first angular distribution relative to the lighting system;
the second light source is configured to generate second light source light with a controllable second radiant flux, wherein the second radiant flux is dimmable over a second dimming range; wherein the second light source light has a second angular distribution relative to the lighting system, different from the first angular distribution;
the control system is configured to control the first light source and the second light source, wherein, in a controlling mode of the control system, the control system is configured to control a value of one of the first radiant flux and the second radiant flux with a negative proportional dependence of a change in a value of the other of the first radiant flux and the second radiant flux over at least a respective part of the respective dimming range,
wherein the first light source is configured to generate the first light source light providing one or more of a first horizontal illuminance Eh1 and first vertical illuminance Ev1, wherein during operation of both the first and the second light source at equal power the second light source is configured to generate the second light source light providing one or more of a second horizontal illuminance Eh2 and second vertical illuminance Ev2, wherein Eh1>Eh2, and wherein Ev2>Ev1.
