Frequently Asked Questions About LED Light Therapy

After decades of research found that certain wavelengths of light within the red, blue and infrared bands were very beneficial to living tissue. LED Light therapy is a growing segment of Phototherapy treatments that are currently being used in clinical and home settings around the world. Light therapy has been in use by the medical profession to increase circulation and reduce pain for more than 20 years. Its growing acceptance has become more abundant as research continues into the many ways light therapy can help.

HealthLight is a photo-modulated (pulsed, light emitting diodes) device also known as low-level light therapy (LLLT). Based on award-winning Phototherapy science, near-infrared and visible red LEDs are the heart of the HealthLight LED Light Therapy systems. They provide, safe, gentle, but powerful non-coherent light.

Almost everyone can use HealthLight devices to increase circulation and reduce pain as needed. HealthLight is used both in clinics and by patients at home.
Some of the many professionals using HealthLight include:

  • Chiropractors
  • Podiatrists
  • Physical Therapists
  • Massage Therapists
  • Home Health Agencies
  • Light Therapists
  • Medical Doctors
  • Registered Nurses

The differences are significant. Many online products lack the clinical strength to achieve the results needed. Industry-leading HealthLight devices have these advantages:

  • Quickest treatment time of any LED light therapy pads
  • LEDS are optimally placed within neoprene pads
  • Combination of red and infrared light for ideal penetration and efficacy
  • HealthLight products operate at body temperature, unlike other products
  • Highest quality, most durable components
  • The most powerful LEDs in the market – clinical strength
  • No seams – therapy pads won't split or fray
  • USB-style connectors, no breakable DIN connectors

Patient health is too important to risk with anything but the most proven quality products. HealthLight has been a leader in the field for 15 years. It is one of the few manufacturers to produce products only in the USA.
Why do you use light you cannot see?
Light wavelength is measured in nanometers (nm). The human eye only sees the colors of the rainbow. Infrared is outside of the visible spectrum and cannot be seen by the human eye. Our LEDs are tuned to a specific red wavelength that treat surface conditions. Infrared light wavelengths penetrates deeper into human tissue. The two wavelengths working in combination cause a cascade of beneficial, healing effects.

Yes. There are no restrictions on who can use light therapy. It has been successfully used in clinics and homes for two decades.

HealthLight creates a comforting, warm feeling with the pads. The HealthLight pads operate at body temperature, causing no discomfort.

The infrared light energy releases nitric oxide from hemoglobin and endothelial cells. Nitric oxide, "the molecule of life," is a signaling molecule that relaxes smooth muscle cells found in the arteries, veins, and lymph vessels. When these muscles relax, the vessels dilate, thus allowing increased circulation. Visualize the difference in diameter between a straw and a hose – that's an example of vasodilation.

You can use the our LED devices up to three (3) times per day in the same area. Additional usage may not provide additional benefit. Research has shown you should allow a few hours between treatments if you are treating the same location.


We sometimes hear from individuals who are disappointed with their results. Most of the time, if they ensure they are strapping the pads directly on the skin and positioned as directed, using the pads 3x daily and keeping the pad applied for the full 20 minute session, results will dramatically improve. 

Light is beneficial to humans. How it's harnessed and applied is different, depending on whether a light therapy or laser device is used. A major difference is the coherence of the light.
