Red Light Dose Index
The Holistix Red Light Dose Index is a human-readable reference page for the machine-readable red light therapy dosage dataset published by the Holistix Open Biohacking Data Project.
This page summarizes red light and near-infrared dose terminology, common measurement concepts, safety cautions, and device specification fields. It is designed as a structured educational reference, not as a treatment protocol.

This dataset is for educational and informational purposes only. It is not medical advice, diagnosis, treatment guidance, or a substitute for consultation with a qualified healthcare professional.
Red light and near-infrared devices vary widely in wavelength, irradiance, distance, beam angle, treatment area, session duration, pulsing behavior, heat output, intended use, and manufacturer instructions. Dose language should be interpreted carefully.
Red Light Dose Reference Topics
| Topic | Reference Type | Plain-Language Meaning | Safety Note |
|---|---|---|---|
| Wavelength | Technical context | Red light and near-infrared devices are commonly described by wavelength, usually measured in nanometers. | Different wavelengths may have different tissue interaction profiles, and wavelength alone does not define dose. |
| Irradiance | Dose variable | Irradiance describes the light power delivered to an area, commonly expressed as milliwatts per square centimeter. | Irradiance depends on device output, distance, beam angle, and measurement method. |
| Fluence | Dose variable | Fluence describes energy delivered per unit area, commonly expressed as joules per square centimeter. | Fluence depends on irradiance and exposure time. More is not automatically better. |
| Distance | Measurement context | The distance between the device and the skin can strongly affect delivered light intensity. | Compare devices only when distance and measurement conditions are disclosed. |
| Session duration | Use context | Session time is one component of delivered dose, but it should be interpreted with irradiance, area, and wavelength. | Follow manufacturer instructions and avoid assuming longer sessions are always better. |
| Eye safety | Safety context | Bright red or near-infrared lights may require eye-safety precautions depending on device design and exposure conditions. | Follow manufacturer eye-protection instructions, especially for facial use or high-output devices. |
| Heat and skin sensitivity | Safety context | Some devices may produce warmth or heat depending on output and session length. | Stop use if discomfort, irritation, overheating, or unusual symptoms occur. |
| Specification transparency | Buyer caution | Useful red light device documentation should disclose wavelength, irradiance at distance, treatment area, recommended distance, and session guidance. | A vague “red light dose” claim is less useful than clear device specifications. |
