TWO WAVELENGTHS · DIFFERENT DEPTHS

Red Light vs. Near-Infrared

Both wavelengths are widely studied, but they interact with tissue differently.
Read the Full Comparison

Red Light

660 nm

Visible red light is commonly studied for more surface-level exposure.

  • Visible red-light wavelength
  • Primarily interacts with more superficial tissue
  • Studied in skin-focused research
  • Explored for cellular response pathways

Near-Infrared Light

850 nm

Near-infrared wavelengths are studied for deeper tissue penetration than visible red light.

  • Beyond the visible light spectrum
  • Generally penetrates farther than red light
  • Studied in muscle and joint applications
  • Explored in recovery-related research
