Most of us must have imaged running under the blue sky with the floating white cloud. It’s is a pity that we spend the majority of our time under a ceiling and even are chain to the desk. Some researchers came up with a idea to move the sky into the office. And this dream is realized with LEDs.
This brilliant idea was tested for several times as the researches need to make sure the fluctuations are the most similar with daylight.
Now the imitation sky is for sale but not cheap. If you want to work under the sky, you may have a try.
