The junk light epidemic

Can’t relax? The problem is staring you in the face

History of blue light, sunset view

History

For 99.99% of human existence, blue light was only present during the day. The sun went down, blue light faded, and our body knew it was time to sleep.

Modern blue light smart home

Fast forward

Now, blue light is everywhere. Screens and artificial lighting expose us to junk light long after sunset, tricking the brain into thinking it’s still daytime.

man can't sleep

Why this matters

This delays melatonin production and keeps the nervous system alert at unnatural hours – leaving us feeling wired instead of tired.

A Modern Solution

The Tri-Color Circadian Bulb supports your focus, relaxation, and sleep with three optimized lighting modes. Simply click the light switch on and off to change mode.

Daily impact

The result? Your natural sleep rhythm is restored, helping your body recover and wake up properly rested.

The Science of Circadian Light

Research into healthy light exposure shows that both the intensity and timing of light matter. An international group of experts in circadian and sleep science recommends:

Day

At least 250 melanopic EDI lux during daytime hours to provide a strong daytime light signal.

Evening

Less than 10 melanopic EDI lux during the three hours before bed to minimise light’s impact on the circadian system.

Night

Less than 1 melanopic EDI lux during sleep – ideally keeping your sleeping environment as dark as possible.

One Bulb. Three Stages of Your Day.

That’s why we created the Swanwick Circadian Light Bulb.

Rather than using the same type of light from morning until bedtime, it gives you three purpose-built settings designed to help create a light environment that changes with your day.

Circadian Tri-Color Light Bulb

The Swanwick Circadian Light Bulb adapts to your day with three purpose-built light settings designed to support your natural circadian rhythm — from focused daytime light to warm evening light and deep red light before bed.

Three Circadian Light Modes

Focus

  • 4000K natural white light • 580 lumens
  • Supports productivity and visual comfort while reducing digital eye strain.

Relax

  • 1600–1700K warm amber light • 500 lumens
  • Helps reduce overstimulation and transition your body out of "go mode."

Sleep

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

How It Works

Simply toggle your existing wall switch to cycle through Focus, Relax, and Sleep modes.

Low Flicker Technology

Designed with a low-flicker driver and independently tested to perform well below accepted industry flicker limits for a more comfortable lighting experience.

Specifications

  • Power: 4W LED
  • Voltage: 110–130V
  • Base: E26 (North America)

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.
