LED Spacing for Optimal Penetration in Red Light Therapy: Mind the Gap

LED Spacing for Optimal Penetration in Red Light Therapy: Mind the Gap

Red Light Therapy devices come in many forms. But is there an optimal design? Or do they all bring us to the same level of effectiveness in the long run? Is it better to have continuous, uniform coverage over an entire treatment area - or are some gaps and spaces between LEDs acceptable? For example, consider these pictures. Will the "uniform" coverage on the left always be better, or would the more "spotty" coverage on the right would be sufficient? The left side may additionally benefit from the convergence of beams from multiple LEDs and wavelengths. The right side the...

The Wavelength Equivalence Guide to Red/NIR Light Therapy

The Wavelength Equivalence Guide to Red/NIR Light Therapy

Do we need specific wavelengths of light to produce different benefits with Red and Near-Infrared (NIR) light therapy? If so, if we want all the clinical benefits then we would need to buy devices with multiple wavelengths or have many devices for different applications.  How close do wavelengths need to be on target? If a study used 810nm, could you not get the same result with 850nm? If a study used 670nm, could you not use 660nm? How far away from a wavelength can you be to have assurance that you would get the same result? +/- 1nm, +/- 5nm,...

Heat Hinders Penetration With Red Light Therapy: Cold Increases Transmittance

Heat Hinders Penetration With Red Light Therapy: Cold Increases Transmittance

Photobiomodulation is the science behind Red Light Therapy. It is defined as a non-thermal application of light on biology. Most studies do not cause significant heating as reported in the literature. Thus, non-thermal treatments are the evidence-based way of doing clinical grade PBM. As brands and influencers try to normalize heating with PBM, they can only make speculative claims by extrapolating from the non-thermal studies. More importantly, they conveniently ignore the potential downsides of combining heating with PBM.  One factor that is commonly overlooked is how heating affects penetration depth.   How Heat Hinders Penetration: Heating the skin before or during...

How Many Watts is Red Light Therapy? Total Joules Dosing Calculator!

How Many Watts is Red Light Therapy? Total Joules Dosing Calculator!

How many Watts do you need for full body Red Light Therapy?  A consumer could obtain the latest generation overpowered LED panel system and not have to worry about having inadequate power. If anything, they would do well to turn down the power and only use the maximum settings for specific purposes (or never).  In another recent interview Professor Glen Jeffery gives caution: "Most of which are far too powerful, you do not want to put vast amounts of energy into your body, you really don't." https://youtu.be/ak5gHOOYdLg?si=b0rLkrP-ECu1GAyF&t=2394 How can we be assured we are getting adequate energy doses without excessive...
