ThyRed is a neck-worn light therapy device. It uses red light (630 and 660 nm) and near-infrared light (830 nm), aimed at the area around the thyroid.

It is built for daily wellness use. Follow the user manual when you wear it.

The band is skin-safe silicone. Our manufacturer is certified to ISO 13485 and ISO 9001. The device has passed FFC testing. Our EMF readings stay below 3 milliGauss — among the lowest in any consumer light-therapy device.

Included in the package:

• ThyRed BASE device
• Controller unit
• USB-C 240W cable 1M
• USB-C PD 20W power plug (US plug)

The ThyRed device is used by both home users and wellness-oriented professionals. It is designed for independent use as part of a personal wellness routine. ThyRed is intended for general wellness purposes and is not designed to diagnose, treat, cure, or prevent any medical condition. A growing body of scientific research explores the biological effects of red and near-infrared light. Users commonly report perceived benefits related to relaxation, stress support, sleep quality, energy regulation, and overall well-being when exposed to targeted light. Individual responses may vary, and specific outcomes cannot be guaranteed. No known adverse effects are associated with normal use of the device. Users are encouraged to consult a qualified healthcare professional and conduct their own research before use. The information provided is for educational purposes only and is not a substitute for professional medical advice.

ThyRed follows a moderate-irradiance, time-based exposure model — even, controlled light over a set session, not peak output.

• Wavelengths: 630 nm + 660 nm (red) and 830 nm (near-infrared), ±10 nm
• LED array: 6 × 630 nm, 6 × 660 nm, 15 × 830 nm — weighted toward NIR
• Emitters: 27 high-efficiency single-wavelength LEDs
• Coverage: 55 cm² treatment area
• Total power draw: 5,000 mW
• Power source: PD USB-C — 5V / 9 V / 12 V, or a USB-C PD compatible plug or power bank
• Weight of device on neck: 80 g
• Material: skin-safe silicone band with a soft velcro strap
• Session timer: 15 / 30 / 60 min
• Intensity: 4 levels
• Controls: 3 buttons — power, session time, intensity
• Operating temperature: 0–25 °C (32–77 °F)

ThyRed uses targeted red and near-infrared light (630 nm | 660 nm | 830 nm) to interact with cellular energy processes in the thyroid region. At these wavelengths, photobiomodulation has been studied for its ability to support mitochondrial function — the system responsible for ATP (cellular energy) production. Unlike high-intensity devices that rely on peak power, ThyRed is engineered around a controlled, moderate irradiance model. Research in light biology shows that cellular response follows a biphasic pattern — meaning optimal results occur within a specific dose range, not at maximum intensity. By delivering evenly distributed light over time, ThyRed supports healthy cellular energy metabolism, balanced oxidative stress response, local circulation, and natural tissue maintenance processes. This precision-dosed approach prioritizes stability, repeatability, and consistent exposure — rather than extreme output.
