Cone Activated
Circadian Lighting

We're going to get a little bit into the science here, but we think our customers want to know how things really work. At TUO, we believe that transparency on how and why our products work is what customers deserve.

Most Circadian Rhythm Lights on the Market are Based on Blue Light. Some lighting products feature warm/cool color shifting throughout the day, blue-enriched, or night modes on screens. They work by activating (or not activating by removing blue color) the non-visual melanopsin in your eye sending “action potentials” to your internal clock, but melanopsin is very insensitive to light. This is because it's not a part of your vision forming system. Influencing melanopsin requires unbearably bright light levels to have any significant impact on your internal clock.
