In this conversation, Ulysse brings a rare perspective: a lighting industry insider who has followed the science of light and biology deep enough to conclude that his own industry may be part of the problem. He and his colleague Jeremy Fielding took spectrometers into the retail stores of Oxford Street and Regent Street in London to measure light quality in environments that should, above all others, be getting it right. What they found was revealing — and in some cases, absurd. He also shares how wearable light-measuring technology exposed just how little infrared light he was absorbing on even his most "outdoorsy" days — and what that means for the rest of us spending our lives under LED lighting. Ulysse draws a compelling parallel between the industrialization of food and the industrialization of light: we've been fed, but we're not being nourished. And he makes the case that red light panels, now booming as a consumer wellness product, are simply supplementation for something our indoor environments have quietly stripped away.
