CLASS 4 LASER VS RED LIGHT/COLD LASER VIDEOS

 Red Light Therapy primarily uses LED bulbs, similar to standard household lighting, to emit therapeutic light. These LEDs typically operate at lower power levels (wattage) and within a wavelength range of 600-800nm. Due to this lower wattage and wavelength, red light therapy is limited in its ability to reach deep tissues, making it most effective for surface-level skin concerns. 

LLLT (Low-Level Laser Therapy), also known as Cold Laser Therapy, uses a Class III laser with less than 1 watt of power. The terms  “low-level” or “cold”, simply refers to the fact that class III lasers produce less heat in the tissues than a class IV laser. Operating in the 800-1100nm wavelength range—similar to infrared lasers—LLLT can produce comparable tissue responses but requires much longer treatment times due to its low power.
