Abstract

Certain aspects involve lighting systems relating to control of light fixture dimming. For instance, a lighting system may include a first light source that outputs a first light color and a second light source that outputs a second light color. The lighting system also includes a switching device that couples and decouples the second light source in parallel with the first light source. The switching device includes a first setting that couples the second light source in parallel with the first light source and enables a variable color dimming operation. The switching device also includes a second setting that decouples the second light source from the first light source and enables a static color dimming operation.
