There's no doubt that light affects our health and well-being. Plenty of studies prove the impact of daylighting and access to views on the health, productivity and safety of building occupants. And yes, medical and educational outcomes can be improved. "But the question is, whether or not we're able to use electric lighting in buildings to provide the same health benefits that we know daylight provides. And that question, I don't think, has a defined answer yet," said Brent Protzman, director of building science and standards development at Lutron Electronics. We can carefully time changes in spectrum and intensity of lighting in buildings, but we have limitations of space, equipment, and energy and safety codes; not to mention accommodations for visual tasks.
