The Role of Circadian Clock Proteins in Innate and Adaptive Immunity

"Subjects that are to be exposed to blue light will be provided by the research personnel with a Day-Light Classic 10,000 lumen SAD light, a device that has been used in many of the previously listed published studies (Epilepsy Behav. 2012 Jul;24(3):359-64. doi: 10.1016/j.yebeh.2012.04.123. Epub 2012 May 30.) The light is small (4 X 16 X 21 inches) and weights less than a pound. It is UV filtered and glare free. There is a single On/Off switch. It will be attached to a rolling stand.~This light is fitted with a blue spectrum filter (peak 442 nm) such that it produces 1700 Lux of blue spectrum lighting when positioned at a distance of 12 inches from the subject. Those subjects assigned to blue light will be asked to shine this small portable blue enriched light on themselves from 0800 to 2000 for 3 days."
