N2 - Research in the late evening and at night has shown that acute activating effects of light are particularly sensitive to short-wavelength light. Yet, findings on such effects during daytime are still inconclusive. This study (N=39) investigated effects of correlated colour temperature (CCT; 2700 K vs. 6000 K, 500 lx on the desk) on individuals’ experiences, performance, and physiology during one hour of exposure in the morning versus afternoon. Except for a higher subjective vitality in the 6000 K condition in the morning, results showed no significant activating effects, and even subtle performance-undermining effects in the high CCT condition. Moreover, participants rated both their mood and the light settings as less positive in the 6000 K vs. 2700 K condition. It is therefore questionable whether lighting solutions with commonly experienced intensity levels should provide a higher CCT during daytime office hours
