The Science of Light. The Promise of Health.
Korrus was founded on a simple but profound belief: light should work in harmony with the human body. For over a decade, our team of physicists, engineers, and data scientists have advanced the frontier of light and health – earning more than over 500 patents, and groundbreaking work with Nobel Laureate Shuji Nakamura along the way.
