RedDuo Pro is a hands-free, headset-style red and near-infrared light device for relaxing light sessions around the ears, jaw, throat and neck. Two independent light modules rest gently on each side, so you can keep reading, working or unwinding while you enjoy your daily wellness routine.

Each side combines 650 nm red light with 850 nm and 940 nm near-infrared light. The flexible frame can also be positioned around the knee or shoulder for a comfortable light session wherever you want to relax.

Key Features

  • Three wavelengths: 650 nm red, 850 nm and 940 nm near-infrared light from tri-wavelength LEDs.
  • Hands-free headset design: Cordless and comfortable, worn like headphones for everyday use at home or at the desk.
  • Dual independent modules: Left and right sides are controlled separately for flexible comfort.
  • 4 output modes: Mild, Normal, High and High Pulse (10 Hz pulsed light), up to 120 mW/cm² in High mode.
  • Flexible timer: 10, 20 or 30 minutes, or continuous, with automatic shut-off.
  • Smart skin-contact sensor: LEDs light up only when the module is close to the skin, helping reduce light toward the eyes and save battery.
  • Rechargeable: 1400 mAh battery in each module (2800 mAh total), USB-C charging; more than 2 hours per full charge (about six 20-minute sessions), and usable while charging.
