A lighting system, comprising:

• a truncated conical visible light reflector having an internal light reflective surface defining a cavity, and having an end and another end being mutually spaced apart along a central axis, the end permitting light emissions from the lighting system;
• a light source being located at the another end of the truncated conical light reflector and including a semiconductor light-emitting device, the semiconductor light-emitting device being configured for emitting, along the central axis in the cavity, light emissions having a first spectral power distribution;
• another visible light reflector, the another light reflector being located in the cavity and having another light reflective surface facing toward the another end of the truncated conical light reflector, the another light reflector being spaced apart along the central axis at a distance away from the semiconductor light-emitting device;
• a volumetric lumiphor being located in the cavity along the central axis between the semiconductor light-emitting device and the another light reflector, and being configured for converting some of the light emissions into additional light emissions having a second spectral power distribution being different than the first spectral power distribution;
• wherein the another light reflector is configured for causing portions of the light emissions and of the additional light emissions to be reflected by the another light reflective surface;
• wherein the truncated conical light reflector is configured for causing some of the portions of the light emissions and additional light emissions, after being reflected by the another light reflective surface, to then be further reflected by the light-reflective surface and to bypass the another light reflector to be emitted from the end of the truncated conical light reflector;
• and
