Search the Photobiomodulation Database for studies on health conditions:

This is the EMF Channel database of light therapy study doses. After getting the results, click to view more study details. Only successful studies are included. 99% of the studies here are on humans, not animals. This database is a work in progress. Many thanks to Vlad for his PBM database. When the data here references his work, the detail page includes a link to the PBM spreadsheet.

About the EMF Channel Light Dose Database

Many people purchase red light therapy or neuromuscular electrical stimulation devices without knowing optimal doses for the results they want to see. The right dose is especially key to light therapies, which have optimal windows of wavelength and energy delivered. Treatment doses outside of those windows will nullify results or harm the user. I took the results from successful EMF studies when these studies included:

Photobiomodulation (Red Light Therapy, Blue Light Therapy, Low Level Light Therapy)
Transcutaneous Electromagnetic Nerve Stimulation (TENS)
Pulsed Electromagnetic Field (PEMF) Therapy
Neuromuscular Electrical Stimulation (NMES)

Many studies do not report exact dose parameters they used. They are therefore not included here, even the study reported a therapeutic result.

Table: Light Dose Parameters

Term	Parameter
Time	Seconds
Power	Milliwatts (mW) or Watts (W)
Total Dose Energy	joules (J) = power x time = Watts x seconds
Wavelength	Nanometers (nm)
Frequency	Hertz (Hz)
Spot Size	Squared Centimeters (cm^2)
Duty Cycle	Percentage of time light source is on per cycle
Power Density	Watts per centimeters squared (W/cm(2) = power / probe size
Fluence	Joules per Centimeters Squared (J/cm^2) = total energy delivered by the probe size
