LED light therapy · Photobiomodulation
Inlight Therapy uses red, near-infrared, blue, and green light energy to support your body’s natural healing processes. It is a gentle, drug-free, non-invasive way to help relieve pain, reduce inflammation, improve circulation, and speed recovery.
What is Inlight Therapy?
At the heart of every Inlight Therapy system is a science called photobiomodulation, or PBM. Flexible neoprene pads hold arrays of LEDs that emit specific wavelengths of light. Your cells absorb that light energy and convert it into biological action: more energy, faster repair, less inflammation, and better circulation.
The key to the improvement in blood flow is nitric oxide, a short-lived gas that relaxes the arteries, helps regulate blood pressure, fights free radicals, and discourages platelets from clumping together in the blood vessels.
Sessions are painless. Most people simply feel a gentle warmth. The pads are portable, easy to place, and don’t require constant monitoring, which makes them practical for both home and clinical use.
Specific wavelengths reach different layers of tissue, from the skin’s surface down to muscle, joint, and bone.
Red and near-infrared light stimulate the mitochondria, boosting ATP, the energy your cells run on.
Nitric oxide is released, relaxing blood vessels and bringing more oxygen and nutrients to the area.
Tissue repair, reduced inflammation, and relief that can last hours or even days after a session.
The colors of light
Different colors of light carry unique properties. That lets them reach different layers of tissue and trigger different beneficial responses.
450–470 nm
Works closest to the skin’s surface. Powerful antimicrobial properties make it especially effective at targeting acne-causing bacteria, supporting clearer skin, and promoting wound hygiene. Also plays a role in mood and alertness.
570 nm
Known for calming, balancing effects. Supports acute and chronic pain relief, circulation, and reduced inflammation, as well as wound healing and skin health. Emerging research suggests it may ease seasonal mood (SAD) and migraine discomfort.
630–650 nm
Reaches deeper into skin and underlying tissue, where it stimulates the mitochondria. The boost in cellular energy (ATP) speeds tissue repair, reduces inflammation, and supports collagen for healthier, more resilient skin.
850–930 nm (avg. 880 nm)
Goes deepest of all, reaching muscles, joints, and even bone. Particularly powerful for pain relief, muscle recovery, circulation, and supporting the healing of deeper tissues.
Why some LEDs look “off”: near-infrared light is invisible to the human eye, so every other row of LEDs may appear unlit during a session. They are working. Near-infrared is paired with every pad except the Facemask.
Benefits
Many people with symptoms of pain or impaired circulation experience positive results using Inlight Therapy. Benefits build with consistent use, though even one session can bring a noticeable shift.
FDA indications for use: to temporarily relieve minor pain, stiffness, and muscle spasms, and to temporarily increase local blood circulation. Other benefits listed reflect manufacturer materials and emerging research; individual results vary.
“PBM simply gives your cells the light energy they need to do what they’re already designed to do — just better.”
Inlight Therapy Owner’s Manual
Progressive Multi-Pulse™ technology
Inlight’s proprietary pulsing delivers light at specific frequencies rather than a steady glow. Pre-programmed AUTO settings cycle through a sequence automatically, so every session is simple: power on, press start, and relax.
AUTO A 2-Port & 6-Port PRO
Pulses red, blue, and infrared light through all seven of Dr. Paul Nogier’s frequencies across the 20-minute session. French neurologist Dr. Nogier proposed that tissues and organs resonate with specific frequencies, and that re-exposing tissue to its normal resonance helps the body rebalance. A great way to start the day.
AUTO B 6-Port PRO only
Pulses light at a series of pure-tone Solfeggio frequencies. Designed to help shift the nervous system out of “fight or flight” and into a calmer state of rest, digest, and heal. Stress is a major barrier to the body’s healing response.
AUTO C 6-Port PRO only
A blend of Nogier settings 2, 3, 4, and 6 with lower Solfeggio frequencies. A balance of relaxation and cell renewal, often chosen for healthy aging and for recovery from injury.
| Setting | Frequency | Traditionally associated with |
|---|---|---|
| 1 | 73 Hz | Cellular health and circulation, chronic recurring problems, endocrine function; acupuncture and trigger points |
| 2 | 147 Hz | Scar tissue; inflammation associated with injuries and infection |
| 3 | 294 Hz | Skin and nerve, wounds, eye injuries, after surgery; universal acupuncture frequency |
| 4 | 587 Hz | Neuropathy, circulatory and lymphatic stimulation, GI tract, liver, pancreas; tendon, ligament, and joint injuries |
| 5 | 1,174 Hz | Bone, joints, ligaments, tendons; relaxation of large muscle groups |
| 6 | 2,349 Hz | Chronic conditions not responsive to settings 3 or 5; lymphatic system and plateaus |
| 7 | 4,698 Hz | Pain control; sedates trigger points; excess calcification with chips, spurs, and arthritic conditions |
Frequency associations are based on Dr. Nogier’s research as summarized by Inlight Therapy representatives. Each manual setting can be used on its own for a longer, focused session.

Controllers
System packages
Pads and controllers are bundled into systems for specific needs, from a single-pad travel kit to a full six-pad clinical setup.
Who it’s for
What to expect
Connect the power supply to the controller and a grounded 110V outlet. Plug your pad(s) into any open socket on top of the controller.
Position the pad over the area with the LED side gently against clean skin. Secure it with the elastic strap, using light pressure only.
Turn the controller on. The session runs for 20 minutes in AUTO mode and shuts off on its own.
Safety & quality
The light from Inlight Therapy devices is within the visible to infrared spectrum and consists of non-ionizing radiation, with no ultraviolet light, which the manufacturer notes is safe for use.
If you have specific health concerns, check with your healthcare provider before beginning light therapy.
Questions
No. Photobiomodulation is painless and non-invasive. Most people feel only a gentle warmth during a session.
Many people notice a shift after a single session, and benefits increase with regular use. Because increased circulation triggers responses that last hours or days, some conditions respond well to as few as three 20-minute sessions per week.
No training or certification is required. Systems are ready to use right out of the box, and the AUTO settings are a great place to start. An authorized representative can help you explore manual settings and pad placement.
Those are the near-infrared LEDs. Infrared light is invisible to the eye, so those rows appear unlit even though they are working alongside the colored LEDs.
Yes. Inlight Therapy uses visible and near-infrared light only. It is non-ionizing and contains no ultraviolet light.
Apply pads to clean skin. Avoid creams, gels, or lotions before or during a session.
Yes. Inlight Therapy is used by children, adults, older adults, athletes, and pets, as well as by many kinds of practitioners. Consult your healthcare provider or veterinarian about your specific situation.
Wipe non-porous pads with a cloth sprayed with a hospital-grade disinfectant (1:10 bleach-to-water). Don’t soak, submerge, or autoclave any part. Store in a cool, dry place between 32–110°F, and avoid creasing pads or wrapping cords around them.
Every new device carries a two-year warranty, and repairs are available for the life of the device. Contact your authorized representative or visit Inlight Therapy’s reconditioning and repairs page. Don’t open the controller or pads yourself.
