Understanding Red Light Therapy Wavelengths

Understanding Red Light Therapy Wavelengths

The world of red and near infrared (NIR) light therapy is an exciting one, but also a confusing one. If you've tried red light therapy then you know it's like trying to find your way in a dark maze. Are higher wavelengths better than lower ones? Should you use cool or warm lamps? What about combining red and NIR light? In this article we will do our best to shed some light on this matter to help you make the right purchase for you.


Red light is, in essence, the light wave at the furthest end of the electromagnetic spectrum or the visible spectrum. This is the furthest point that one can see in any direction. To clarify, you will not be able to see any light after you pass this point.

You could be able to experience wave qualities that are outside of this range, especially in the way that you may feel heat or temperature. On the other hand, you will only be able to see the light as red up to 730 nm in wavelength. In addition, the spectrum contains waves that fall within the NIR and IR groups. They are almost similar in function because their wavelengths and frequencies are quite similar to one another.

Today, some LED devices have the ability to emit red lights as well as infrared and near-infrared waves. Some examples of medical-grade devices that have received FDA approval are the Lumitter Pro Targeted Red Light Therapy Panel and the Lumitter Full Body Red Light Therapy Panel. Both of these panels are designed to treat large areas on the body.

The Benefits Of RedLight Wavelengths (610-670)

One of the most popular and therapeutic a wavelengths is the 660nm in red light spectrum. The red light wavelengths are able to carry out a wide array of functions despite their ability to go deep inside the tissues.

You need to get certain high-quality devices that can ensure pure light therapy to take advantage of these advantages. One such device example is the Lumitter Tabletop Red Light Therapy Panel. The following is a list of some of the most important functions of red light:

  • Reducing inflammation: Red light therapy has been proven to be effective in reducing inflammation, which is one of the major causes for a wide range of diseases including pain, swelling and stiffness.
  • Treating acne: Red light therapy also helps in preventing acne by killing bacteria that causes it while reducing inflammation around infected areas caused by overactive sebaceous glands located on your skin surface.
  • Reducing pain: This type of therapy has been known as an effective way to reduce pain related conditions such as arthritis, sports injuries and muscle soreness after intense workouts or exercise sessions where you might have overused muscles that resulted in painful conditions such as cramps or tightness around them due to overexertion during workouts or exercises periods when doing so many repetitions at once

The Benefits Of Near-Infrared Light Wavelengths (820-850)

Wavelengths of 850 nm often provide the most beneficial results regarding NIR radiation. There is a remarkable ability for them to penetrate bone to bone.

The effects of NIR, on the other hand, are not only harmless but also generally advantageous to the neural system. The following are the primary effects that NIR light wavelengths have:

  • It effectively repairs the traumatic consequences of any brain injury and protects nerves from further damage.
  • Enhances physical performance while also facilitating faster recovery.
  • Stroke patients, especially those who have had their stroke for less than 90 days, have been proven to benefit from these waves in clinical studies.
  • Promotes bone development, which in turn helps to promote overall bone health.
  • In addition, it assists in the healing process of wounds.
  • The use of NIR may assist in correcting misaligned teeth.
  • It effectively treats sprains, strains, ligament tears, tenosynovitis, tendonitis, and tenosynovitis, among other conditions.

How Deep Do the Wavelengths Penetrate?

 Red light has a wavelength range of 610 to 670 nanometers. This means that it is within the visible spectrum, but it is not as bright as other colors. Red light can penetrate around 4 to 5 millimeters deep into the skin, which is about half the thickness of your fingernail.

In general, photoreceptors are required for tissues or cells to absorb red light or any other kind of light wave. However, these waves have lower frequencies, they can pass through obstacles for as long as their energy permits.

NIR wavelengths, on the other hand, are the most penetrating. The wavelength of these waves extends more than 750 nm and up to 850 nm. They are able to penetrate the skin, soft tissue, muscle, and connective tissues, and they can even go into the bones! Therefore, they penetrate far further than 5 millimeters, almost 2 inches.


The benefits of Red Light Therapy are many and varied, but the most important thing to remember is that it is an effective method for treating a number of conditions.

The technology has been around for some time now, but it's only recently that we have started to see its true potential. There are many different types of equipment available that can offer you relief from pain or help you recover from an injury.

However, if you want to make sure you are making the right choice when purchasing this kind of device, you need to be aware of the various factors involved in purchasing one. If you need further assistance on Red & NIR light therapy please contact us at Lumitter for more information.
