What is the Pulse feature in the Red Light Panels?Updated 7 hours ago

When NIR pulse mode is activated, the red light stays on continuously while the invisible near-infrared light rapidly pulses at the selected frequency (such as 40Hz). This allows users to enjoy the skin-supporting benefits of continuous red light while applying pulsed near-infrared energy to deeper tissues such as muscles and joints. Because near-infrared light is invisible, it can be pulsed without creating noticeable flicker or discomfort.  

A 40Hz setting means the NIR LEDs turn on and off: 

40 times every second 

NIR:
ON OFF ON OFF ON OFF...
(40 cycles per second)

Red:
ON ON ON ON ON ON... 

The red light remains constant while the NIR component is pulsed. 

Why Do Manufacturers Pulse Only the NIR? 

1. The Red Light Remains Visible 

If red LEDs were pulsed, users would see noticeable flickering. 

Even at higher frequencies, some people may perceive: 

• Flickering 
• Eye strain 
• Discomfort 

By keeping the red LEDs continuously illuminated, the panel appears bright and stable. 

2. NIR is Invisible 

Since NIR light cannot be seen, manufacturers can pulse it without creating a distracting visual effect. 

The user experiences: 

• Constant visible red illumination 
• Pulsed NIR delivery behind the scenes 

3. Most Interest in Pulsing is Focused on Deeper Tissue Applications 

Many pulsing studies focus on: 

• Muscle recovery 
• Joint support 
• Deep tissuephoto biomodulation
• Neurological applications 

These are primarily areas where NIR is already the dominant wavelength due to its deeper penetration.
