Light Dose Database

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.

590 nm Light Effect on Lipid Droplets and Hormone-Sensitive Lipase

Wavelength(s):
590, 660, 410, 457, 505, 530
Irradiance:
Condition:
Fat
Title:

Amber Light (590 nm) Induces the Breakdown of Lipid Droplets through Autophagy-Related Lysosomal Degradation in Differentiated Adipocytes

Goal:

Researched irradiated human fat with 410 nm, 457 nm, 505 nm, 530 nm, 590 nm, and 660 nm low level light. 590 nm “significantly reduced the concentration of lipid droplets” and increased lipid autophagy (broke down fat). In documenting the science of photobiomodulation, I rarely come across a study that finds significant effect at one wavelength, and no effect at nearby wavelengths. That did happen in this study. 590 nm affected fat breakdown and 505 nm did not. The abstract did not mention the other wavelengths tested. Presumably they were also insignificant, so it’s unclear why 505 nm was singled out as ineffective.

Condition:
Fat
Title:

A double-blind, placebo-controlled randomized trial evaluating the ability of low-level laser therapy to improve the appearance of cellulite

Goal:

Use green 532 nm diodes without massage or mechanical manipulation to improve the appearance of cellulite in thighs and buttocks.

Researchers treated 34 women with low-energy green light.

Subjects receives three treatments a week for 2 weeks (6).

Researchers treated subjects’ hips, thighs, a waist. Treatments lasted 30 min.

Subjects had significant:

decrease in circumference of treated areas
decrease in baseline body weight
reduction in BMI
reduction in cellulite

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.
