In Uppsala, Sweden, darkness falls early in winter. This means children have only a few hours of daylight each day to go out and play. So, with the help of the city government and lighting design consultancy Bjerking, we launched an experiment with our innovative Connected LED-lighting, Philips CityTouch. We wanted to see if we could we give a class from a local kindergarten more time to play outside in Tegnerparken and help improve the quality of their lives.
