Independent, peer‑reviewed research from the University College London group studying what happens when indoor light regains its long wavelengths.
A single 15‑minute exposure to 670 nm deep red light, given before a standard oral glucose tolerance test, reduced the rise in blood glucose over the following two hours. The proposed mechanism: long‑wavelength light stimulates mitochondria, which consume more glucose as they produce more energy.
Standard LED lighting spans roughly 350–650 nm. When it was supplemented with broad‑spectrum light reaching into the near‑infrared (400–1500 nm+) for two weeks, in a real working environment, colour contrast sensitivity improved significantly — and the improvement outlasted the intervention.
Deep Red LIVING is the production model of the lamp supplied to UCL for their recent studies — the same lamp we make today.
On how energy‑efficient lighting removed near‑infrared from indoor life, what that means for mitochondria and metabolism, and the research at UCL.
