Low Level Laser Therapy 650nm - 810nm LF2


Laser LLLT


The LF2 is a stand-alone portable laser class 3R to be worn directly on the skin via a cover and a strap. It is composed of 33 lasers of 650nm in square and three lasers of 808nm for a complementary action in depth. It therefore brings together the best of these two fundamental frequencies of radiation used for this type of therapy. For more information about this mode of therapy, please refer to the Introduction section of this section for therapeutic applications that use the laser. The device operates in stand-alone mode with a rechargeable battery.


Laser LLT


Application areas:

Its fields of application are the same as the LF1. It has more laser diodes (33 of 650nm and 3 of 808nm) than the LF1. The average time of a daily session is 20 minutes (up to 3 times a day). The device heats up in use. It is therefore not a heat effect generated by the laser light on the body but the device which by its operation heats without presenting a concept of dangerousness. 3 laser diodes in the center of the device (see photo) are in the not visible spectrum of 808nm. This is not a failure of the device but only a non-visible feature.

  • Body pain: neck, dorsal, cervical, lumbar, waist, legs, muscle, knee, arthritis, rheumatoid arthritis, fibromyalgia, tendinitis, redness, swelling, morning stiffness.
  • Wound healing
  • Rehabilitation after sports injuries
  • Prostatitis
  • Good effect for menstrual colic
  • Angine
  • Mastitis
  • Hemorrhoids
  • Tennis elbow
  • Tendonitis
  • Bursitis
  • Carpal tunnel syndrome
  • Fibromalgia
  • ...


Therapeutic theory:

The cold laser acts primarily on a mitochondrial protein (cytochrome c oxidase) to increase ATP and reduce oxidative stress. A cascade of downstream mitochondrial and intracellular effects leads to improved tissue repair and reduced inflammation.
