Abstract
Certain aspects involve lighting systems in which the color temperature of the illumination can be selectively modified. In one example, a lighting system can include a set of light sources. The lighting system can also include a switching device. The switching device can connect different light sources from the set into light-source combinations having different color temperatures, respectively. A light-source combination can include two of the light sources connected in series.
