Abstract

Sensors and lighting components are provided that are capable of matching an emitted color to a color observed at a remote location. The sensor measures a light characteristic at a first location, and provides data to a remote lighting component, such as via a wireless connection. The lighting component is configured to emit light based upon the light characteristic, and thus is able to match an observed lighting condition. The lighting component may match the color, intensity, temperature, pattern, texture, or other characteristic of light at a remote location.
