A system includes at least one lighting device, e.g., at least one LED luminaire, and a control circuit configured to control a spectral output produced by the at least one lighting device responsive to environmental information about an area illuminated by the at least one lighting device. The control circuit may be configured to control a color temperature of the illumination responsive to the environmental information. In some embodiments, the control circuit may be configured to lower the color temperature of the illumination responsive to the environmental information indicating a level of reflected light and/or a weather condition, such as precipitation, correlated with the presence or likely presence of glare.

Glare-reactive lighting apparatus

a lighting fixture includes a power input configured to be coupled to a power source, a power output configured to be coupled to an external load and a lighting device, such as a light emitting diode (LED) device, coupled to the power input and configured to provide illumination. The lighting fixture further includes a protection circuit coupled between the power input and the power output and configured to detect a condition of a power source coupled to the power input and to control power transmission between the power input and the power output responsive to the detected condition. The power output may be configured to support daisy-chain connection of the lighting fixture to at least one other lighting fixture, and the protection circuit may be configured to control power transmission to the at least one other lighting fixture responsive to the detected condition.
