You can sit right next to your Flowlight panel or several meters away – it’s completely up to you. The only thing that changes is the treatment time, not the quality of the light itself.
The light spreads at an angle of approximately 180 degrees, meaning it doesn’t beam straight out in a narrow line. This means that the precision decreases at longer distances, but the light wavelengths and therapeutic effect remain the same.
Example of light intensity at different distances:
-
15 cm → approx. 175 mW/cm²
-
30 cm → approx. 140 mW/cm²
-
90 cm → approx. 70 mW/cm²
-
300 cm → approx. 20 mW/cm²
The farther away you are, the longer the session needs to be to achieve the same effect.
