3.4 What Light Frequency (in Hz)
is the Best to Use? - Difference
Between Steady and Pulsed RLT
As an everyday example, continuous light is like leaving a flashlight on steadily, while pulsed light
is like rapidly flicking it on and off. Recent research suggests that pulsed light therapy might have
some advantages over continuous light in certain medical treatments. Here‘s why:
