Illumination change and the earth, from morning until noon, increased brightness and illumination, color also from changes to white blue red orange, while in the afternoon instead. '

small's column', explains: 'on May 15, from the point of view of psychology, is the best lighting solutions, a day is a day in the sunshine time is longer, better spectral components. '

scientists pointed out that these variable illumination apparatus for can be used to solve the astronauts on the international space station and the long space flight circadian rhythm disorders problems that may occur.
