Lighting systems, methods, and devices for protecting human circadian neuroendocrine function during night use are described. Suitable lighting conditions can be provided for a working environment while protecting the circadian neuroendocrine systems of those occupying the illuminated workplace during the night. Lighting systems, methods, and devices can provide substantive attenuation of the pathologic circadian disruption in night workers. Lighting systems, methods, and devices can attenuate the specific bands of light implicated in circadian disruption. LED lighting systems, methods, and devices can provide increased intensity at a different portion of the spectrum than conventional LEDs, providing a useable white light even when unfavorable portions of the wavelength are attenuated by a notch filter. LED lighting systems, methods, and devices can switch between a daytime configuration and a night time configuration, wherein the daytime configuration provides unfiltered light and the night time configuration provides filtered light.
