Since the discovery of a new photo sensor in our retina, in 2001, our understanding of the impact of light on our health has undergone a paradigm shift. We now realize, that the existing lighting environments, created with our limited understanding, has turned our days into night and our nights into day, impacting our health adversely.

This alarming disconnect from healthy  light and dark cycle has resulted in increasing prevalence of many lifestyle diseases and problems like, insomnia, depression, mood disorders, obesity, overeating, heart diseases and hypertension, diabetes, cancer etc either directly or indirectly. But the lighting environments in our homes and offices, still does not accommodate this new found understanding, continuing to negatively affect our health at an imperceptible  pace and intensity.
