CLEARLIGHT® INTRODUCES SUN ONE®: A TARGETED UVB SOLUTION FOR EVERYDAY WELLNESS
New 295 nm UVB Wellness Lamp Designed Around a Wavelength Studied for Supporting the Body’s Natural Vitamin D Production
BERKELEY, CA. – October 8, 2026 –Clearlight®, The Original Red Light Infrared Sauna™, global industry leader and early pioneer of infrared sauna technology and integrated wellness solutions, today launched the SUN ONE® Wellness Lamp, a new medical-grade wellness solution that easily delivers UVB light for general health and wellness. SUN ONE adds UVB light into anyone’s daily routine and is especially useful for those who may not otherwise get enough time in the sun. SUN ONE is designed for use as a standalone wellness experience or integrated into your Clearlight infrared sauna session, along with Clearlight’s other wellness therapies such as red light therapy, halotherapy (salt), and aromatherapy. Stacking modalities optimizes the healing potential when these therapies are used together during a normal infrared sauna session.
The SUN ONE Wellness Lamp delivers targeted UVB light at 295 nanometers (“nm”), which is a wavelength range studied for its role in supporting the body’s natural production of vitamin D and healthy inflammatory responses. UVB light has also been widely studied in dermatology for its effects on skin and in connection with conditions such as psoriasis, vitiligo, and eczema. Designed with precision LED technology and integrated safety features, SUN ONE makes targeted UVB light easy to incorporate into a modern wellness routine.
According to data from the National Institutes of Health and national health surveys, about 42% of U.S. adults are clinically deficient, while nearly two-thirds have overall insufficient levels.(1) It is estimated that over a billion people worldwide are vitamin D deficient.(2) Vitamin D is a key component for building muscle, keeping bones healthy, and maintaining and optimizing immune function. While spending time outdoors can be a good source of Vitamin D, that option is not always available.
“Over the last 30 years, Clearlight has built its reputation by engineering and manufacturing the highest quality infrared saunas,” said Dr. Raleigh Duncan, founder of Clearlight. “We have spent the last decade researching, testing, and refining SUN ONE, and with its debut we can now offer a greater range of wavelengths along with our leading therapies, which include red light, salt, and aromatherapy, as well as other offerings for healing.”
Why Vitamin D Matters
Vitamin D has earned the nickname “the sunshine vitamin” for good reason. Unlike most vitamins, it’s primarily produced by the body itself, triggered when skin is exposed to certain wavelengths of ultraviolet B (UVB) light. While it can also be obtained through certain foods and supplements, sunlight remains the body’s most efficient natural source of vitamin D production. Vitamin D acts like a hormone in the body, regulating calcium absorption, bone mineralization, and immune function while also regulating protein synthesis, growth, and performance in skeletal muscles.
Precision Where It Matters Most
Unlike broader-spectrum devices on the market, SUN ONE uses advanced, narrow-band LEDs with a peak wavelength of 295 nm, the specific UVB wavelength most effective for supporting the body’s natural process of producing Vitamin D.
SUN ONE’s proprietary, patent-pending design uses solid-state UVB LED technology engineered around a precise 295 nm peak. The LEDs allow for a compact, rechargeable design and skip the ongoing cost of replacing fluorescent bulbs, so the wellness device is precise, long-lasting and virtually maintenance-free.
“SUN ONE provides the exact wavelengths that the body requires without producing adjacent UVB and UVA wavelengths that the older devices deliver,” noted Dr. Duncan.
Built for Safety and Simplicity SUN ONE was designed with guided, built-in safety features that make it very approachable for first-time users as well as experienced wellness enthusiasts to use at home or for business:
Distance sensor: alerts users if they are too close or too far away for a usable dose. This keeps every session in the optimal range
Skin-type selection with voice prompts, based on the Fitzpatrick Skin Type scale, automatically recommends the appropriate session according to the user’s skin type
Protective eyewear reminder: Voice reminder to always wear the protective eyeglasses included with the SUN ONE device
One-session-per-day design: safe, structured use rather than open-ended exposure
Portable and rechargeable: ergonomic handle with multi-position stand offers flexibility for tabletop/flat surface use or inside a Clearlight infrared sauna
Multiple languages: Instructions are audible and can be set for up to 10 different languages

Designed to Stack With the Clearlight Sauna Wellness Suite
SUN ONE was designed and engineered to work independently or inside a Clearlight Sauna. The articulating arm and rechargeable design make it easy to bring directly into a sauna session, allowing anyone to combine a SUN ONE session with their infrared sauna. The whole concept has evolved to allow the stacking of many therapies while in the sauna without requiring more time for each therapy to be enjoyed.
“We deeply understand how heat, light, cold, salt, aroma, and vibration work together as we’ve been doing this since the day we started,” said Dr. Duncan. “It’s the intentional layering of complementary modalities that produces a feeling of well-being. We built SUN ONE so people could add this remarkable therapy into their healing session, combining light and heat therapy to get more out of the time they’ve already set aside for their wellness routine.”
