Red Light Therapy Learning Center
Red Light Therapy Learning Center
A single place to find the AWA guides on dose, distance, wavelengths, safety basics and choosing a home device.
These guides explain how red light therapy devices work and how to read a spec sheet. They are written to help you compare devices and use them the way the label says. They are not medical advice, they do not diagnose or address any condition, and they are not a substitute for a conversation with a qualified healthcare professional.

Frequently asked questions
What are the Learning Center guides?
They are plain language guides that explain how red light therapy devices work, how to read specifications such as wavelength, irradiance and distance, and what to check before you buy. They describe devices and specs. They are not medical advice.
Where should I start if I am new?
Start with the buyer's checklist for home use, then read the dose guide. Together they cover the specs worth comparing and how output, distance and session time fit together.
How do I compare two devices fairly?
Compare wavelengths, the irradiance listed at a stated distance, the size of the lit area, the timer and the warranty. Then read each product page and label for what applies to that specific device.
Who writes these guides and how are they kept current?
The AWA team writes them. Because AWA sells devices, our Editorial Standards page discloses that potential bias and explains our sources, our update process and how to report an error.
