Are you ready to take light therapy to the next level?


Due to the pulsing of light in this video, do not  watch if you have a history of light induced migraines, vertigo, seizures.

“This review of the literature indicates that overall pulsed light may be superior to [continuous wave] light with everything else being equal.”

Pulsed light is the turning on and off of light at specific frequencies (Hz). The LightpathLED pulses between 0 and 10,000 times per second. It can be manually programmed or you may choose any of the 10 presets. You also have the option to choose continuous wave. As more research is coming out, we are learning how pulsed light has benefit above and beyond non-pulsed (continuous wave) light found in most other panels and red light therapy modalities. Particularly this has been shown in reduction of inflammation/pain and improving brain function (trauma, emotional issues, memory, sleep).

The below articles discuss pulsing benefits as well as the specific presets in the LightpathLED Pulsed panel.

Effect of Pulsing in Low-Level Light Therapy

"(Here are possible) biological reasons for the improved efficacy of pulsed light (PW) over CW (continuous wave). The majority of the pulsed light sources used for LLLT have frequencies in the 2.5–10,000 Hz range and pulse durations are commonly in the range of a few millisecond. This observation suggests that if there is a biological explanation of the improved effects of pulsed light it is either due to some fundamental frequency that exists in biological systems in the range of tens to hundreds of Hz, or alternatively due to some biological process that has a time scale of a few milliseconds. Two possibilities for what these biological processes could actually be occur to us. Firstly, it is known that mammalian brains have waves that have specific frequencies []. Electroencephalography studies have identified four distinct classes of brain waves [,]. Alpha waves (8–13 Hz) occur in adults who have their eyes closed or who are relaxed []. Beta waves (14–40 Hz) mainly occur in adults who are awake, alert or focused []. Delta waves (1–3 Hz) occur mainly in infants, adults in deep sleep, or adults with brain tumors []. Theta waves (4–7 Hz) occur mainly in children ages 2–5 years old and in adults in the twilight state between sleeping and waking or in meditation []. The possibility of resonance occurring between the frequency of the light pulses and the frequency of the brain waves may explain some of the results with transcranial LLLT using pulsed light.

Secondly, there are several lines of evidence that ion channels are involved in the subcellular effects of LLLT. Some channels permit the passage of ions based solely on their charge of positive (cationic) or negative (anionic) while others are selective for specific species of ion, such as sodium or potassium. These ions move through the channel pore single file nearly as quickly as the ions move through free fluid. In some ion channels, passage through the pore is governed by a “gate,” which may be opened or closed by chemical or electrical signals, temperature, or mechanical force, depending on the variety of channel. Ion channels are especially prominent components of the nervous system. Voltage-activated ion channels underlie the nerve impulse and while transmitter-activated or ligand-gated channels mediate conduction across the synapses.

There is a lot of literature on the kinetics of various classes of ion channels but in broad summary it can be claimed that the time scale or kinetics for opening and closing of ion channels is of the order of a few milliseconds. For instance Gilboa et al. [] used pulses having a width 10 milliseconds and a period of 40 milliseconds (25 Hz). Other reports on diverse types of ion channels have given kinetics with timescales of 160 milliseconds [], 3 milliseconds [] and one paper giving three values of 0.1, 4 and 100 milliseconds []. Potassium and calcium ion channels in the mitochondria and the sarcolemma may be involved in the cellular response to LLLT [].

Thirdly there is the possibility that one mechanism of action of LLLT on a cellular level is the photodissociation of nitric oxide from a protein binding site (heme or copper center) such as those found in cyctochrome c oxidase []. If this process occurs it is likely that the NO would rebind to the same site even in the presence of continuous light. Therefore if the light was pulsed multiple photodissociation events could occur, while in CW mode the number of dissociations may be much smaller."

What are Nogier Frequencies?

Back in the 1970s, a French neurologist named Paul Nogier discovered an array of light frequencies that the human body recognizes and utilizes to its benefit. From there, Nogier frequencies were born, and are still utilized for their medicinal benefits to this day.

Nogier’s discovery was based on his research on the effects of varying frequencies on the tissues of the body. He found that “sick cells” tend have vibratory characteristics that are different from that of the healthy tissues. As he furthered his studies on these natural frequencies, he found that healthy tissues tend to vibrate on a spectrum of seven unique frequencies. That being said, Nogier found that by exposing sick tissues to the natural frequencies of the healthy version of these tissues, healing would be provoked.

Nogier frequencies are the most popular pulse frequencies that are used in photobiomodulation treatments, especially for healing purposes. Depending on the specific Nogier frequency that is pulsing, there are various levels of healing that can take place. From the surface level of the skin healing to remediation of organs that lie deep within the body.

For instance, Nogier frequency A is most beneficial for wound healing and other issues that are located on the surface of the skin.  Nogier frequency B is great for treating lung and liver problems, as well as issues that may be within the GI tract. There are several other Nogier frequencies that provide benefits that range from the healing of physical flesh or alleviating pain, to lessening the effects of depression and other intolerable mood disorders

Descriptions of the Key Frequencies


According to Dr. Nogier, sickness results when cells, molecules or particles of matter are out of their normal resonance or vibratory pattern. By repeatedly exposing damaged tissue to the normal resonance frequencies associated with that tissue, healing often occurs, sometimes quite rapidly.

Dr. Nogier developed a unique pulse test. This test enabled him to determine that all tissues and organs throughout the body (which develop from three basic embryologic tissues; ectoderm, endoderm and mesoderm) are in resonance (sympathetic vibration) with specific frequencies.


Based on these findings, he designed electronic instruments that delivered seven pulsed energies into the body for the purpose of healing injured or diseased organs and tissues. These pulsed energies induced healing by exposing damaged tissues to their normal resonance frequency.

  1. (73 Hz.) For use when cellular activity is hypoactive, such as chronic recurring problems, nonunion fractures and chronic splints and for stimulation of osteoid. It is also helpful in activating humoral and endocrine functions. Field work has shown this setting helpful in stimulating (tonifying) acupuncture and trigger points and increasing circulation in areas being treated, such as wounds when past the acute stage.
  2. (147 Hz.) For areas of yellow scar tissue that are generally formed internally on tendons, ligaments and sub-acute (lingering but not chronic) conditions. Field use has shown this setting to be helpful in reducing inflammation associated with injuries and infections. This is often called the universal frequency because most problems involve inflammation.
  3. (294 Hz.) For tissue of ectodermal origin, such as body openings, skin and nerve. Field applications include wounds, eye injuries and after surgery. Setting 3 tends to tone tissue while minimizing the chance of hemorrhaging fresh wounds or recent surgical sites. It is also good for the treatment of acupuncture and trigger points, corneal ulcers and ulcerated mucous membranes. This is called the universal frequency in acupuncture.
  4. (587 Hz.) This frequency appears to be most effective for neuropathy, but also for circulatory and lymphatic stimulation and treatment of tissue of endodermal origin, such as GI tract, liver and pancreas. In field applications, setting 4 has been used in conjunction with 5 and 2 for tendon, ligament, joint and other injuries where reaching secondary levels of tissue is needed.
  5. (1174 Hz.) For tissue of mesodermal origin, such as bone, joints, ligament, viscera and tendon. Field experience has shown setting 5 to be especially good for tendon and ligament injuries when used with 4 and 2. It also helps in relaxing large muscle groups.
  6. (2349 Hz.) For chronic conditions not responsive to setting 3 or 5. Field experience shows setting 6 to be a good supplement to 3 when healing processes appear to reach a plateau.
  7. (4698 Hz.) For pain control, primarily when C nerve fibers are transmitting to dorsal root ganglia and when involvement of neurotransmitters is of physiological importance. Field experience shows 7 to help suppress pain and to sedate acupuncture and trigger points and aid in diminishing excess calcification associated with chips, spurs and arthritic conditions.
