Understanding irradiance (light intensity)
Irradiance describes how much light energy reaches a surface, typically measured in mW/cm².
Importantly, irradiance changes with distance, higher numbers closer to the panel, lower numbers further away.
The values below reflect typical output ranges, not guarantees, and should be interpreted as guidance rather than targets.
Approximate irradiance by distance
| Distance from panel | Approx. irradiance | Coverage footprint |
|---|---|---|
| 15 cm | >200 mW/cm² | ~89 × 25 cm |
| 30 cm | ~168 mW/cm² | ~89 × 30 cm |
| 45 cm | ~140 mW/cm² | ~99 × 40 cm |
| 60 cm | ~125 mW/cm² | ~109 × 50 cm |
| 90 cm | ~98 mW/cm² | ~119 × 61 cm |
How to interpret these numbers
Higher irradiance does not automatically mean better results.
In real-world use:
-
Standing closer increases intensity but reduces coverage
-
Standing further back lowers intensity but increases usable area
-
Most people benefit from moderate, repeatable sessions, not maximum output
Session length, comfort, consistency, and distance all matter more than chasing the highest possible number.
Practical usage notes
-
The panel should feel comfortably warm, not hot
-
Excessive heat is a signal to increase distance or reduce session time
-
Follow device guidance and adjust gradually based on comfort
Red light therapy devices are designed for general wellness use, not medical treatment.
