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 / device specification,Measurement concept,No,Red light masks / red light panels / red light wraps / consumer wellness devices,2026-06-26,https://www.holistixintl.com/pages/red-light-dose-index,Red light therapy devices,"Wavelength is a specification field, not a standalone dose claim.",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 photobiomodulation 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,Basic terminology / device specification,Measurement concept,No,Red light masks / red light panels / red light wraps / consumer wellness devices,2026-06-26,https://www.holistixintl.com/pages/red-light-dose-index,Red light therapy devices,Irradiance values can vary by testing method and distance.,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,Basic terminology / dose concept,Measurement concept,No,Red light masks / red light panels / red light wraps / consumer wellness devices,2026-06-26,https://www.holistixintl.com/pages/red-light-dose-index,Red light therapy devices,Fluence is a dose-related concept but should not be used as a treatment recommendation.,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 delivered 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,Device specification / buyer education,Device comparison,No,Red light masks / red light panels / red light wraps / consumer wellness devices,2026-06-26,https://www.holistixintl.com/pages/red-light-dose-index,Red light therapy devices,Distance is one of the most important missing details in many consumer device comparisons.,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,Buyer education / consumer safety caution,Usage context,Yes,Red light masks / red light panels / red light wraps / consumer wellness devices,2026-06-26,https://www.holistixintl.com/pages/red-light-dose-index,Red light therapy devices,Session duration should not be presented as a medical protocol.,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,Red light masks / red light panels / red light wraps / consumer wellness devices,2026-06-26,https://www.holistixintl.com/pages/red-light-dose-index,Red light therapy devices,Eye safety language should stay cautious and non-medical.,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 photobiomodulation 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,Red light masks / red light panels / red light wraps / consumer wellness devices,2026-06-26,https://www.holistixintl.com/pages/red-light-dose-index,Red light therapy devices,"This is a comfort and safety caution, not treatment guidance.",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,Device comparison,No,Red light masks / red light panels / red light wraps / consumer wellness devices,2026-06-26,https://www.holistixintl.com/pages/red-light-dose-index,Red light therapy devices,This row supports transparent comparison without making clinical claims.,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."
