Version 1.2 update: Added row-level citation fields to the CSV and JSON structures, including source_name, source_url, and citation_note. These fields make the dataset more citation-ready while preserving the v1.1 source/evidence classification structure.

Important Disclaimer

This dataset is for educational and informational purposes only. It is not medical advice, diagnosis, treatment guidance, dosage guidance, disease-prevention 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.

For a beginner-friendly guide to interpreting these dose terms, read Red Light Therapy Dose Explained.

Red Light Dose Reference Fields

The table below uses plain-language dose and safety categories with visible source/evidence classification and row-level citation notes. The v1.2 CSV and JSON include expanded row-level fields such as source_type, evidence_level, claim_type, medical_disclaimer_required, commercial_relevance, last_reviewed, related_holistix_page, related_product_category, notes, source_name, source_url, and citation_note.

The v1.2 CSV and JSON now use the same row-level source, evidence, and citation framework so both downloadable formats describe the dataset consistently.

Red Light Dose Reference Topics

Record ID	Topic	Reference Type	Plain-Language Meaning	Safety Note	Source / Evidence Type	Evidence Level	Claim Type	Medical Disclaimer Required	Source Name	Source URL	Citation Note
HOL-RL-DOSE-0001	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.	Compare wavelength claims carefully. Wavelength should be interpreted with irradiance, distance, treatment area, and session duration.	Educational terminology / device specification context	Basic terminology	Measurement concept	No	Unlocking the Power of Light on the Skin: A Comprehensive Review on Photobiomodulation	https://www.mdpi.com/1422-0067/25/8/4483	Use as broad review support for red and near-infrared wavelength terminology, skin-facing PBM context, and the distinction between red/NIR device categories. Do not use as a disease-treatment claim.
HOL-RL-DOSE-0002	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.	Irradiance should be interpreted only when distance and measurement conditions are disclosed.	Educational terminology / dose measurement context	Measurement caution	Measurement concept	No	Under the spotlight: mechanisms of photobiomodulation concentrating on blue and green light	https://pmc.ncbi.nlm.nih.gov/articles/PMC6685747/	Use for the concept that photobiomodulation effects depend on radiometric parameters including wavelength, irradiance, dose, and delivered photons. Use as measurement-context support, not protocol guidance.
HOL-RL-DOSE-0003	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.	Avoid assuming that higher fluence or longer exposure automatically produces better results.	Educational terminology / dose calculation context	Measurement caution	Measurement concept	No	Dosimetry for photobiomodulation therapy: response to Sommers	https://pmc.ncbi.nlm.nih.gov/articles/PMC4885889/	Use for dose/dosimetry caution and biphasic-response context. Supports the idea that more energy is not automatically better.
HOL-RL-DOSE-0004	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.	Distance changes delivered intensity, so dose comparisons should include measurement distance.	Educational terminology / measurement condition context	Measurement caution	Measurement concept	No	Photobiomodulation for pain relief: Model-based estimates of effective parameters	https://pmc.ncbi.nlm.nih.gov/articles/PMC11482420/	Use for the idea that light reaching target tissue depends on optical properties and that tissue-level irradiance/fluence can differ from emitter output. Supports cautious distance and measurement-condition language.
HOL-RL-DOSE-0005	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.	Follow manufacturer instructions and avoid extending sessions beyond recommended guidance.	Educational terminology / usage context	Usage caution	Usage context	Yes	Brain Photobiomodulation Therapy: A Narrative Review	https://pmc.ncbi.nlm.nih.gov/articles/PMC6041198/	Use for biphasic dose-response context and the need to interpret exposure parameters carefully. Do not convert into session-length recommendations.
HOL-RL-DOSE-0006	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.	Eye protection guidance should follow manufacturer instructions, especially near the face or with high-output devices.	Safety guidance / consumer device use context	Consumer safety caution	Safety caution	Yes	Safety Profile of Slit-Lamp-Delivered Retinal Laser Photobiomodulation	https://pmc.ncbi.nlm.nih.gov/articles/PMC7396177/	Use as eye/retina safety-context support showing that eye-facing PBM safety depends on wavelength, irradiance, delivery method, and controlled conditions. Keep manufacturer eye-protection language.
HOL-RL-DOSE-0007	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.	Stop use if discomfort, irritation, overheating, or unusual symptoms occur.	Safety guidance / skin comfort context	Consumer safety caution	Safety caution	Yes	Bio-Heat Transfer and Monte Carlo Measurement of Near-Infrared Transcranial Stimulation of Human Brain	https://arxiv.org/abs/2212.03946	Use only as thermal/near-infrared modeling context showing that heat and tissue interaction are relevant considerations. Do not use as clinical proof or consumer protocol support.
HOL-RL-DOSE-0008	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.	Consumers should be cautious when device pages make vague dose claims without clear specifications.	Consumer comparison context / buyer education	Buyer education / device specification	Buyer education	No	Photobiomodulation for pain relief: Model-based estimates of effective parameters	https://pmc.ncbi.nlm.nih.gov/articles/PMC11482420/	Use to support specification transparency: wavelength, irradiance, fluence, tissue delivery assumptions, and measurement conditions should be disclosed when comparing devices.

Source and Evidence Notes

This index uses cautious educational language because red light and near-infrared devices vary by wavelength, irradiance, distance, treatment area, session duration, heat output, and intended use. Entries marked as requiring medical disclaimer language should not be interpreted as personalized medical advice, dosage guidance, or treatment recommendations.

Users should follow manufacturer instructions, use appropriate eye protection when instructed, stop use if discomfort occurs, and consult a qualified healthcare professional if they have medical concerns, light sensitivity, eye conditions, medication concerns, recent procedures, or unusual symptoms.

The v1.2 CSV and JSON add row-level citation fields, including source_name, source_url, and citation_note. These fields are intended to make the dataset more transparent, easier to audit, and more useful for AI/search systems, researchers, journalists, and consumers. Citation notes should not be interpreted as medical claims or product-efficacy guarantees.
