Power Output and Dosing

If you are confused about dosing and power outputs, you are not alone. This subject has become an area of interest for many of the researchers and scientists that study this modality.

To directly quote from the abstract of the article “Review of light parameters and photobiomodulation efficacy: dive into complexity.” that was written by Randa Zein, Wayne Selting, Michael R. Hamblin , and was published in December 2018 in the

“Photobiomodulation (PBM) therapy, previously known as low-level laser therapy, was discovered more than 50 years ago, yet there is still no agreement on the parameters and protocols for its clinical application. Some groups have recommended the use of a power density less than 100  mW/cm2 and an energy density of 4 to 10  J/cm2 at the level of the target tissue. Others recommend as much as 50  J/cm2 at the tissue surface. The wide range of parameters that can be applied (wavelength, energy, fluence, power, irradiance, pulse mode, treatment duration, and repetition) in some cases has led to contradictory results.”

“…tissues were divided into those with higher numbers of mitochondria (muscle, brain, heart, nerve) or lower numbers of mitochondria (skin, tendon, cartilage). Graphs were plotted of energy density against power density. Although the results showed a high degree of variability, cells/tissues with high numbers of mitochondria tended to respond to lower doses of light than those with lower number of mitochondria. Ineffective studies in cells with high mitochondrial activity appeared to be more often due to over-dosing than to under-dosing.”

The standard AAH Lights (red, blue and green) were tested at a local professional light lab with calibrated equipment. We used the Coherent PM30 thermopile power meter attached to a Coherent LabMax-TOP power and energy meter. The following are the results of this testing:

What will you do with this information? This is how you will calculate the amount of energy (joules/cm2) that you are delivering thru the lights. The formula for this is power density (W/cm2) multiplied by time (seconds). We have provided this table for reference –

We tested several competitor lights but are only going to post the results of our lights. It matters to us that you are using our lights correctly and therefore, we have taken this extra step to bring this information to you.

We will post the results of the PBM testing soon.
