Product Information – Intranasal Light Therapy

We have developed three main configuration platforms for different outcomes:

1. 633 nm wavelength LED – available as ” The Life Light 633 Red” by Vielight or “Qi-light”

Qi-light switched on

A non-laser based intranasal light therapy product. The basic specifications include a diode (LED) releasing light with wavelength in the visible red spectrum (633 nm) powered by a managed dosage of energy to illuminate the nasal cavity. It stimulates the body to restore systemic homeostasis through its total-body response to the signals generated by the light, strengthening the condition of the body. It is based on the scientific fact that our cells respond to low-energy light signals by healing itself. Followers of natural energy medicine will identify this as balancing the vital energy or “Qi”. The nostril has been found to be an effective non-invasive channel to introduce these signals that has been created by light energy to be distributed to the various parts of the body and the brain.

2. 655 nm wavelength coherent light – available as “The Life Light 655 Prime” by Vielight or “RadiantLife LT”

RadiantLife LT

This is a premium version of the 633 nm LED intranasal light therapy product. It uses a low level (or “cold”) laser diode to release coherent light of wavelength in the visible red spectrum (655 nm) powered by a managed dosage of energy to illuminate the nasal cavity. The energy generated with this phototherapy version is substantially lower than that for 633 Red resulting in a more power-efficient design. It is not as bright as the 633 Red and more users report better sleep with this model when compared to the 633 Red, although the users of the 633 Red also report good outcomes with sleep disorder. Most of the 3000+ clinical studies on healing with light over the decades have been based on low level (or “cold”) laser of similar parameters. The battery will last longer than the 633 Red before requiring a replacement. As a safety measure, users should not look directly into the light source of this model.

3. 810 nm wavelength, pulsed near-infrared LED – available as “The Life Light 810 Infrared” by Vielight

810 pic

The latest LED model, 810 nm pulsed LED is specifically targeted for the light energy to reach the brain. In theory it should perform comparably to the other two models of shorter wavelengths for circulatory-related conditions but it there are yet insufficient test data to confirm this. However, the wavelength of 810 nm in this model penetrates more directly and deeper into the brain to reach deeper lying glands. Brain cells respond just as well as other cells in the body to this dosage of light energy. This near-infrared red light is invisible to the naked eye. In addition, it is engineered to pulse at 10 Hz, which has been associated with brain oscillation in its alpha state. In studies, this has drawn the greatest neurological healing in traumatized brains. This state also helps to release certain calming chemicals in the brain.

Recommended Usage:
Use daily in the evening (auto-timed for 25 minutes and hands-free) to maintain good health. However, users are encouraged to experiment to determine the routine that gives the best result for his/her mind and body. Users should not compensate missed daily treatments by doing more treatments in a day.

Use maximum of twice daily (with at least 6 hour break) in a health event.


Built to withstand drop tests and normal use; diode has a specified life of 30,000 hours. Known to survive the weight of a truck.

Safety and Regulations

The devices have been tested for electrical safety and rendered safe. It consumes and generates less energy than most consumer electronic devices, and the energy cannot be felt by a normal person. They are compliant with the European CE requirements for safety. However, they have NOT been evaluated by any regulatory body, including the FDA and Health Canada. The company does not make any claim for long-term cures although the evidence shows that regular use may improve the user’s quality of life. All evidence have been based on actual available data with these devices and/or published evidence based on other tests based on similar parameters and scientific bases.
