Configurable lighting system
A system can configure a luminaire for providing illumination of a selected color temperature, a selected lumen output, or a selected photometric distribution. The luminaire can comprise at least two light sources that have different illumination characteristics, for example different color temperatures, different lumen outputs, or different photometric distributions. The system can configure the luminaire to operate a first of the two light sources, a second of the two light sources, or both of the light sources based on an input. When the luminaire is configured to operate both of the light sources, the luminaire can produce illumination having a color temperature, a lumen output, or a photometric distribution that is different than either of the two light sources.
