The California Lighting Technology Center is a not-for-profit research, development and demonstration facility dedicated to accelerating the development and commercialization of next-generation, energy-efficient lighting, and daylighting technologies.
The CLTC discusses circadian-friendly lighting and other lighting innovations in this article.
Circadian friendly lighting may be more beneficial to our health. Blue wavelengths found in CFLs, smartphones and screens, streetlights, and most LEDs tell the brain to wake up and suppress sleep-inducing melatonin. Red and amber wavelengths found more in incandescent lighting and, increasingly, LEDs help produce melatonin and encourage sleep and rest.
