Inspired by Nature. Powered by Game-Changing Technology.
Your home is your sanctuary, and now more than ever you’re spending more time inside of it. More time at home means even more exposure to artificial junk light from lighting fixtures and harsh LED screens — that is, until now. TrueLight’s latest product lineup offers a patented lighting solution that emits specific wavelengths of light to entrain your circadian rhythms as nature intended. This very same technology was originally developed to light up International Space Station. Now, TrueLight is exclusively bringing it you and your family so that your sanctuary can be place of peace, not stress.

Communicates at a cellular level

Boosts energy and productivity

Regulates vital hormones & rhythms

Promotes faster, deeper sleep
How it Works
The all new TrueLight Circadia™ light bulb, powered by BIOS SkyBlue™ LED technology, emits Human
Compatible™ color temperatures that provide the same circadian benefits of the sun during a 24-hour period.
During the daytime, it infuses the critical sky-blue spectrum (490nm) to increase alertness, improve focus and boost your mood. For your safety, the SkyBlue™ technology emits minimal light in the blue light hazard region associated with retinal injury.
At nighttime, the TrueLight™ Circadia™ bulb has a dimmable capability that removes the sky-blue spectrum and creates a warmer atmosphere that promotes natural melatonin production and better sleep.

A Powerful Partnership
The new TrueLight Circadia™ light bulb is a collaboration between:

Biological Innovations and Optimization Systems, LLC (BIOS) is a recognized innovator in LED lighting systems. Their roots trace back to NASA, having originally developed the technology that originally lit up the International Space Station. Today, they continue to be at the forefront of human-centric lighting that is designed to improve the health and well-being of people, plants, and animals, while reducing energy use and creating a more sustainable planet.
Together, we are combining our core value of using quality lighting to improve the quality of life.
Circadian Light is a Healthy Stimulant
Natural sunlight consists of the full visible light spectrum, including red, orange, yellow, green, blue, indigo, and violet light. Blue-enriched light, in particular, is responsible for promoting alertness and productivity during the daytime. The TrueLight Circadia™ bulb emits the critical sky-blue spectrum at 490nm to help stimulate your mind and body and entrain your circadian rhythms.


Circadian Light Improves Sleep Quality
As the sun falls below the horizon each day, dusk’s warmer color spectrum tells the body that it is time to power down and prepare for a great night’s sleep. This is when you naturally begin producing melatonin – the key hormone that aids in triggering deep, restful sleep. The TrueLight Circadia™ bulb intentionally transitions to warmer color settings at night so that you can decompress and get better sleep.
Circadian Light Improves Health and Well-being
Long-term exposure to junk light can throw off your sleep/wake cycle and negatively impact on your health. Circadian rhythm disruption has been connected to a host of health concerns, including but not limited to mood disorders, weight gain, diabetes, heart disease, Alzheimer’s, Parkinson’s and even cancer. Conversely, circadian lighting is specifically designed to support the body’s natural 24-hour body clock. The new TrueLight Cirdacia™ bulb empowers you and your family to thrive in the environment that matters most: your home.
