LED Light Therapy Calculators
Free tools below, designed to calculate accurate treatment times and energy doses for your LED light therapy sessions.
Choose the light therapy calculator you need.
Whether you’re measuring irradiance, fluence (J/cm²), or treatment time, these free tools help you understand and optimise your device’s performance for the best results.
Each calculator works using your device’s measured irradiance (from a spectrometer or solar power meter), your selected distance from the light source, and your preferred session duration.
Together, they help you estimate the total therapeutic energy delivered to your skin, joints, or treatment area — ensuring safe, effective, and repeatable results for both people and animals.
💡 Tip: Always use manufacturer-verified irradiance data or measured readings for the most accurate results.
