Red Light Therapy Dose Calculator
Dose (J/cm²) = irradiance (mW/cm²) × seconds ÷ 1000. Most studied protocols land between 10 and 60 J/cm² per area. Enter your panel's method-verified irradiance, not its marketing number.
60.0 J/cm²
Within the commonly studied 10-60 J/cm² range.
Remember the measurement method
If your panel only publishes a solar meter or method-unstated figure, halve it as a working assumption before calculating, and check whether a spectrometer test exists. See spectrometer vs solar meter.
