Initially, some of our monitoring department colleagues did not trust the new luminaires, because they were accustomed to working in unlit environments, especially at night. Gradually, however, they changed their minds, also with regard to the customised setting options of the lighting intensity. Our colleagues working twelve-hour shifts alternating between night and day shifts, unanimously agreed that the lighting had a positive effect on fatigue and concentration when dealing with everyday activities. Today, therefore, the lighting is used during the day and at night, when it was previously customary to dim all lighting altogether.
