The FlexBeam uses 9 LEDs in total, configured in 3 light pods. Each pod contains two near-infrared (NIR) and one red LED. The wavelengths are:
- Red Light: The device uses 3 red LEDs operating at a wavelength between 610-650nm. This light is ideal for superficial conditions as it penetrates the skin up to 2.5cm.
- Near-Infrared (NIR) Light: There are 6 NIR LEDs with a wavelength between 800-850nm. This light penetrates deeper into the body, reaching up to 10cm, making it effective for muscles, joints, and deep tissue.
