Developed for iGuzzini, the patented Radix ceiling lighting system aims to provide more than a certain level of wattage: rather, the Radix allows the user to control not only the amount, but also the character of light to create a mood of well-being. It is the result of experimentation in photobiology—the biological effects of exposure to light and the nature of variations of daylight in artificial spaces. “I think well-being and light are intimately correlated. As somebody that travels a lot around the world, I see that there is a need for daylight and also to create an atmosphere of light in the evening, to replicate an atmosphere similar to daytime. I think the relationship between the body and light is fundamental, even more fundamental than between the body and food,” said Daniel Libeskind.
