Circadian lighting guide

Circadian lighting changes the color of light inside to mimic the daylight patterns outside. The changing colors throughout the day can stimulate our bodies and minds and help us stay alert and awake. They can also help us unwind and become more relaxed in the evening as we get ready for bed. The key is knowing what color of light to use and when. This booklet will help guide you on a circadian journey to help enhance your every-day interactions with lighting. Get ready to experience an amazing transformation in how you see and use lighting in the comfort of your own home.
