1. A lighting apparatus, comprising:

  • at least one primary general illumination lighting component having an electrical connection and configured to deliver at least one primary general illumination lighting;

    at least one LED-based secondary general illumination lighting component having an electrical connection and configured to selectively deliver at least one secondary general illumination lighting, the secondary general illumination lighting and the primary general illumination lighting resulting in at least one combined general illumination lighting;

    a first sensor configured to detect a first range of optical characteristics from incoming ambient light;

    a second sensor configured to detect a second range of optical characteristics from incoming ambient light; and

    a controller receiving a first sensor signal from the first sensor and a second sensor signal from the second sensor, the controller including a control algorithm to provide an output signal to the at least one LED-based secondary general illumination lighting component, the output signal being based on the first sensor signal and the second sensor signal, the control algorithm used to generate the output signal to adjust the at least one combined general illumination lighting closer to a first optical characteristic target in the first range of optical characteristics and to a second optical characteristic target in the second range of optical characteristics.
