Healthy Lighting Guide

Healthy Lighting Guide cover

Modern home lighting is optimized for cost and convenience, not for human biology. Bright blue-rich light at night suppresses melatonin and disrupts sleep. Flicker from cheap LEDs causes headaches and eye strain. Cool color temperatures throughout the day flatten the circadian signals your body relies on to regulate energy, mood, and recovery.

Our Healthy Lighting Guide introduces the principles of circadian-aware design: what to use during the day, what to switch to in the evening, where flicker and EMF emissions hide, and which fixtures we install in the homes we build.

Better lighting changes how a home feels and how you sleep. It's also one of the easiest upgrades to retrofit.
