Claim:
1. A lighting unit comprising: a first light source configured to generate first light source light, a second light source configured to generate second light source light having a spectral distribution different from the first light source light, a first wavelength converting element able to convert at least part of one or more of the first light source light and the second light source light into first wavelength converting element light, a second wavelength converting element able to convert at least part of one or more of the first light source light, the second light source light, and the first wavelength converting element light into second wavelength converting element light having a spectral distribution different from the first wavelength converting element light, wherein the lighting unit further comprises a transport infrastructure configured to arrange the first light source, the second light source, the first wavelength converting element, and the second wavelength converting element in a first configuration or a second configuration by transport of one or more of these, wherein in the first configuration and the second configuration the lighting unit provides lighting unit light having substantially the same color point while having different color rendering indices.
