Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Light 1
Light 1 will have an altered color composition as compared with a standard LED bulb.
Light - alternate
Light will be given during the night to determine its effects on melatonin suppression. This light will be an LED with an altered spectral distribution (different color)
Light 2
Light 2 will be a standard LED bulb.
Light - standard
Light will be given during the night to determine its effects on melatonin suppression. This light will be an LED with standard spectral distribution
