Circadian Tri-Color Light Bulb

The Swanwick Circadian Light Bulb adapts to your day, helping you stay focused, unwind, and prepare for deeper sleep with three purpose-built light settings designed to support your natural circadian rhythm.

Three Circadian Light Modes

Focus

  • Supports productivity and visual comfort while reducing digital eye strain.

Relax

Sleep

  • 1000K deep red light • 168 lumens
  • Zero blue light to help support natural melatonin production before bed.

Why Swanwick?

Swanwick is the only brand of blue light blockers that have routinely sought third party validation. We've been studied by the University of Washington and the University of Indiana. We've been featured in a study by SleepScore Labs, and had research findings published in the Journal of Applied Psychology and Harvard Business Review.

There is no other brand on the market that has gone to the lengths we have to make the validation of our technology the backbone of our company. Talk is cheap in the blue light world. Why Swanwick? Because our actions speak way louder than their words.
