Out with ‘human centric,’ in with ‘nutritional light’

  • by

Human-centric lighting is lighting devoted to enhancing vision, wellbeing, and performance individually or in some combination, according to Philips Lighting.

Believing that the human-centric lighting movement is lacking momentum, a new advocacy group has emerged to help give things a kick, and has started by rebranding the concept as “nutritional light.”

The non-profit Good Light Group, based in Eindhoven, the Netherlands, aims “to promote the importance of nutritional light on the wellbeing of people,” the foundation said upon its formal launch earlier this month on the International Day of Light, May 16.


“Light is as important as nutrition for the body and brain as vitamins, proteins, minerals. Billions of people are now in light that does not stimulate the body and brain. Our objective is that they can enjoy nutritional light…”


— Jan Denneman


Good Light Group founder and industry veteran Jan Denneman has been a longtime advocate of healthy lighting, having helped put human-centric lighting on the 2017 10-year roadmap for LightingEurope, where he served as president.

Denneman left LightingEurope last year, about a year after leaving a 10-year stint as president of the Global Lighting Association. He also retired in January last year from Signify, then called Philips Lighting, after more than 42 years at the company.


“We have finally learned that light is a nutrient much like food, and like food, the wrong kind can make us ill and the right kind can help keep us well.”
