Keeping Cool with Red Light Therapy: Why We Don’t Mix Light and Heat

Keeping Cool with Red Light Therapy: Why We Don’t Mix Light and Heat
Is it beneficial to mix heat and light? Can we improve the safety and effectiveness of Photobiomodulation by keeping the tissue cool? We explore how it could be advantageous to avoid too much tissue heating during photobiomodulation. And in fact cooling the tissue beforehand can improve penetration and effectiveness!

DIY Flicker Meter and Pulse Measurements! - a how-to guide

DIY Flicker Meter and Pulse Measurements! - a how-to guide

As you know I have been very interested in flicker these past few years. Not only can flicker affect our red light therapy experience, but I find flicker affects me everywhere in my daily life. So why do you want a flicker or pulse meter for yourself? - Measure pulse rate from Red Light Therapy or PBM products. - Test for flicker on your light-bulbs, computer monitors, and LED products. - Test for PWM (pulsed width modulation) in dimming products. - Test for flicker or PWM when using a slow-motion camera doesn't find anything. Well instead of sending every single...

The Solar Power Lie - The Dark Deception of the Red Light Therapy Industry

The Solar Power Lie - The Dark Deception of the Red Light Therapy Industry

Have you been duped into buying a high intensity LED panel that claims a suspiciously round number like 100mW/cm^2 at 6 inches? We often see extremely high intensity numbers being advertised, but these numbers are based on improper measurement tools, techniques, and biased rounding. This blog will help to elucidate the greatest bait-n-switch being performed in the red light therapy industry today. One of the most important parameters of red light therapy is indeed the intensity! This is normally described as the power per square area, in units of milliWatts per Square Centimeter (mW/cm^2). This is a physical quantity that...

Beam Angle for LED Red Light Therapy: Do Degrees Matter?

Beam Angle for LED Red Light Therapy: Do Degrees Matter?

Once you are familiar with all of the important parameters of wavelengths, intensity, flicker, and nnEMF that we cover in previous blog posts, it might be time to dig deeper into what other design choices might be important for Photobiomodulation devices. One interesting topic is the Beam Angle! This describes the angle at which light is emitted from the device. If you can imagine in 3D space, light is being emitted as a kind of semi-spherical cone outward from the light source.  The angle of this cone is important to determine how to best use the device. For example wide...
