We present a spectrometric instrumentation to monitor and log the spectral characteristics of the light in hospital rooms over long term periods during a trial of the effect of controlled lighting on patients. Each room has been equipped with a dynamic lighting system enabling change of correlated colour temperature of the light over the day. The objective is to estimate and document the available light exposure to the patient including the daylight through the window. The calibrated spectral measurements allows for evaluating the stimulus intensities for all five photopigments in relation to both visual and non-visual effects of the light in the rooms.
