Sunlighten

What Sunlighten does

Sunlighten is a privately held US infrared wellness technology company founded in 1999 by Jason Lincoln Jeffers and headquartered in Overland Park, Kansas. The company designs, manufactures, and sells infrared saunas and complementary light therapy products under its core Sunlighten brand (with sub-brands including mPulse, PulseIQ, lumiNIR, and the recently acquired Ice Barrel) to individual consumers and commercial buyers across the United States, United Kingdom, Germany, France, Malaysia, Vietnam, and Singapore.

The company's core technology stack centers on its patented SoloCarbon heating technology and the PulseIQ intelligent infrared platform, which independently delivers four distinct infrared wavelengths (red, near-infrared, mid-infrared, far-infrared) with precision control and pairs them with six science-backed wellness programs (Heart Health, Detox, Relaxation, Weight Loss, Muscle Recovery, Anti-Aging) plus a custom option. Sunlighten holds 30+ patents supporting this technology base. The product portfolio spans three infrared sauna lines (mPulse intelligent, Amplify, Signature), portable and custom saunas, plus complementary hardware including the FDA 510(k)-cleared RED Light Therapy Mask, the lumiNIR handheld LED device, chromotherapy and sound therapy modules, and (since May 2025) Ice Barrel cold plunge products. The company classifies most products as FDA General Wellness rather than medical devices.

Sunlighten operates a hybrid direct-to-consumer and B2B commercial go-to-market model. The primary revenue stream is hardware sales through the company's owned e-commerce platform (sunlighten.com) and dedicated accessory storefront (shop-us.sunlighten.com), with quote-based pricing, financing via Wells Fargo and Klarna, and HSA/FSA support through TrueMed. A commercial sauna division serves fitness centers, gyms, chiropractors, medical practices, wellness spas, and interior designers. The company is actively building subscription recurring revenue via the Sunlight NAD+ Rx telehealth program ($125/month annual plan) launched in 2026 and is leveraging the 14 million annual sessions across its 200,000+ customer base as a data asset to power PulseIQ recommendations. Press coverage in WSJ, Forbes, Well+Good, Popular Science, People, and MSN supports premium positioning.

Core offering

Sunlighten designs, manufactures, and sells infrared sauna cabins across three tiers (mPulse intelligent, Amplify, Signature) plus portable and custom units, all built around patented SoloCarbon heating elements and the PulseIQ platform that independently delivers four infrared wavelengths for targeted wellness programs. Beyond saunas, the company offers complementary wellness hardware — the FDA-cleared RED Light Therapy Mask and the lumiNIR handheld LED device — and has expanded into cold therapy through its wholly owned Ice Barrel subsidiary and clinician-supervised NAD+ injections via the Sunlight telehealth platform.

Product overview

Sunlighten offers a comprehensive infrared wellness product portfolio built around its intelligent PulseIQ platform. The core offering consists of three infrared sauna lines: the flagship mPulse series featuring the PulseIQ intelligent platform that delivers four distinct wavelengths (red, near-infrared, mid-infrared, far-infrared) with precision control and adaptive personalization; the mid-range Amplify series with SoloCarbon heating technology; and the traditional Signature series. The company also offers portable and custom sauna options. Complementary products include the FDA 510(k)-cleared RED Light Therapy Mask, the lumiNIR handheld LED device, Chromotherapy and Sound Therapy modules, and the acquired Ice Barrel cold therapy line. The PulseIQ platform serves as the intelligent layer, powering the mPulse saunas with six science-backed wellness programs and data-driven personalization. The company also operates a telehealth service (Sunlight NAD+ Rx) through its Sunlight brand.
