Light is life. Yet so often we simply take light for granted. Light allows us not only to see and to navigate our surroundings, but it does much more, it also helps us feel good, it helps us function better.

Light is the most important timer for our internal clock. We need light to wake up in the morning and darkness to fall asleep at night The true value of light lies in the combination of excellent visual, biological and emotional benefits. Light affects sight, feeling of safety, orientation, alertness, cognitive performance, sleep/wake cycle, mood, energy and relaxation.
