Healthy Circadian LED Smart Bulbs

TUO lights uniquely activate the eye’s natural circadian color system only recently discovered in 2020. This was found to be 20x more effective than other circadian lights at normal lighting levels.  No need for 10,000 lux bright lights or harmful blue light.  This circadian color lighting is only available from TUO.

Avoid Costly Mistakes With Color

Can you relate to any of these problems?​

  • You missed that opportunity to make a memorable first impression because the colors you wore made you look washed out

  • You are frustrated with shopping because every time you purchase an outfit it always looked better on the model than on you

  • You have wasted money on new cosmetics because they don't match your kin tone

  • That red dress  you like is truly an eye catcher, but all people see is the dress and not you

Your Circadian Rhythm is Off

Your Circadian Rhythm is out of balance if..​

  • you feel tired and irritable all day

  • you are groggy in the morning

  • you don't get a restful sleep at night

  • you have a hard time waking up early

  • you have trouble falling asleep at night

Complex Lighting in a Simple Way

The human biological clock has evolved over thousands of years to be responsive to the sun and sky; and human health is closely related to how the body responds to light cues.

TUO produces a particular spectrum of light that helps to support human circadian health in a simple way.  TUO's smart bulb can be programmed through an app to automatically adjust to set times and schedules and provide light that promotes healthy circadian rhythms.

TUO Creates Rhythm in Your Life

With TUO you will

  • enhance your mood

  • sleep like a baby

  • wake up refreshed

  • improve your energy levels

  • reduce eye strain


As an early adopter of the TUO light, after 2 weeks I can wake up naturally without an alarm clock at the same time every day. The app is great, I didn't realize that it configures a specific daily circadian schedule based on me and my schedule.


"The TUO bulb has been a great addition to my daily routine.  I'm sharper during my morning commute and sleeping better throughout the night. I have waited a long time for technology like this to come around. Thanks, TUO!"
