What Red Light Frequency is Best?

Red light

  • 630 nm
    Used for surface level tissue signaling and circulation
    Often paired with near-infrared
  • 660 nm
    Most commonly used red wavelength
    Supports cellular energy and tissue repair
    Helps with inflammation and blood flow

Near-infrared light

  • 810 nm
    Targets deeper tissue penetration
    Often used for internal or dense tissue areas
  • 830 nm
    Very common for pelvic and abdominal use
    Penetrates deeper than red light
    Supports mitochondrial activity
  • 850 nm
    Deepest penetration of commonly used ranges
    Most popular for fibroids and internal masses

Most people use

  • Combination of 660 nm + 850 nm
  • Or 830 nm + 850 nm for deeper focus

Typical use pattern

  • 10 to 20 minutes per area
  • 3 to 5 times per week
  • Light placed over lower abdomen or pelvic area

What do the lights look like?

How the lights look:

Red light 630 or 660

  • Bright visible red
  • Looks like a deep ruby or cherry glow
  • Clearly lit up even in a bright room

Near infrared 850

  • Looks very dim or almost off
  • Sometimes a faint dull red dot if you’re close
  • In a dark room you may barely see anything
  • In normal light it can look completely dark

Mixed panels

  • The red LEDs look bright
  • The 850 LEDs look much darker next to them
  • This contrast makes people think the 850 isn’t working, but it is
