- Data are least-square means ± standard errors of the means adjusted for the effect of experimental order. Low-low = low-CCT (4500 K) ambient lighting+ low-CCT (5000 K) task lighting; High-low = blue-enriched high-CCT (12000 K) ambient lighting + low-CCT (5000 K) task lighting; RT = reaction time; %RT i = 100 x (RT i)/(RT 1); %Lapse frequency i = 100 x (Lapse frequency i)/(Lapse frequency 1). RT = reaction time.
