Cold LED lighting affects visual but not acoustic vigilance

Previous studies demonstrated that both light intensity and spectral composition of light impact on brain functioning and regulate circadian rhythms. Further, several studies have shown that light exposure, especially blue light (about 460 nm), has positive effects on alertness, vigilance, mood, also increasing mental performance and work productivity. Unfortunately, results have not been always consistent.
