The study "circadian stimulus for CS 0.3

The lighting is a dynamically adjustable light, temperature, output and distribution in order to achieve the 0.3 medium "circadian stimulation". Most of the patients wake up, stay in space, add lighting. Individual illuminance calibrated gauges used for monitoring exposure to light time and other parameters. (Editor: LED James)
