There's More to a Red Light Sauna Than Red Light: Sunlighten Introduces Amplify™ RED powered by near infrared

Full-Body Photobiomodulation Meets a Patented Infrared Combination Only Sunlighten Can Deliver

LEAWOOD, Kan., Sept. 15, 2026 /PRNewswire/ -- Sunlighten, the global leader in infrared sauna technology, today announced Amplify™ RED powered by near infrared, a red light sauna designed around the science of photobiomodulation (PBM) and how light is delivered to the body. It's for people who want the intense heat of a traditional sauna along with therapeutic infrared and red light therapy in one experience.

For more than 25 years, Sunlighten has pioneered the use of infrared light for wellness. Long before red light became a consumer trend, Sunlighten understood the importance of near infrared light and inlaid it directly into its sauna walls. Amplify RED builds on that expertise, bringing visible red light together with near infrared PBM in Sunlighten's hottest, most intense sauna experience, with a patented combination of infrared light and heat technologies only Sunlighten can deliver.

"Putting a red light panel in a sauna isn't the same as engineering a sauna around how light reaches the body," said Sunlighten CEO Aaron Zack. "With Amplify RED, every decision from wavelength and placement to proximity, coverage and dose is informed by how the body actually receives light. That's the difference between adding a feature and architecting based on the science."

How Light Reaches the Body Matters

More power isn't automatically better, and distance matters. Light weakens as it travels, and the body's response to photobiomodulation follows a biphasic curve, meaning the right dose matters more than the highest output. In a sauna, the thermal environment is another consideration. That's why Amplify RED accounts for how both light and heat are delivered, rather than treating light therapy as an add-on.

"We consider thermal biology, how the body responds to heat, and photobiology, how the body responds to light," said Sunlighten Co-founder Connie Zack. "That means purposeful delivery of wavelength, dose, proximity, placement and whole-body coverage, because what reaches the body matters for the wellness experience."

Purpose in Every Layer

Every layer of Amplify RED has a purpose, bringing together light, infrared and material technologies in one sauna experience:
 

• Red + near infrared PBM — complementary wavelengths purposefully positioned throughout the sauna, with attention to dose, proximity, placement and whole body coverage.
• Patented SoloCarbon® far infrared — Sunlighten's proprietary far infrared heater technology, with up to 99% emissivity for a complete therapeutic infrared experience.
• Full-spectrum infrared — delivers Amplify RED's hotter, more intense sauna experience, reaching up to 170°F.
• CELLIANT® infrared fiber — a performance textile used in the heater coverings that captures body heat, converts it into infrared energy and reflects that energy back toward the body.

The PBM and infrared systems can be controlled independently, giving users the flexibility to experience PBM with or without the higher heat generated by the full spectrum system and customize their light-and-heat experience through dedicated push-button controls and remote start with the Sunlighten mobile app.

Sunlighten also enhanced Amplify RED's heat environment, with improved insulation, a double pane glass door and refined temperature control to help reach and maintain temperatures up to 170°F. The result is a hotter, more traditional sauna-like experience for customers who want intense heat alongside the therapeutic far infrared and red + near infrared PBM Sunlighten is known for.

A Patented Innovation Story Years in the Making

Amplify RED builds on an approach Sunlighten pioneered in 2010, when mPulse® became the first sauna to combine near infrared light into the far infrared sauna. Long before red light became a consumer trend, Sunlighten recognized the importance of near infrared and made it part of the sauna itself.

Today, the two sauna collections apply that expertise in different ways. mPulse, powered by PulseIQ™, offers intelligent, app-guided infrared and PBM + infrared wellness protocols with independent wavelength control. Amplify RED brings integrated PBM to Amplify's hotter, higher-intensity sauna experience for customers who want red + near infrared light alongside full-spectrum heat.

Together, they reflect a philosophy that has guided Sunlighten for more than 25 years: the science of light should inform the way a sauna is engineered.
