  • The Vielight Neuro Duo combines two of our transcranial photobiomodulation (tPBM) devices with Vielight's patented intranasal technology. The Neuro Alpha (10Hz) and Neuro Gamma (40Hz) are included in this convenient and economic combo package. You can now enjoy the option of 10 Hz and 40 Hz pulsed photobiomodulation via two separate control units, one common transcranial headset and one intranasal applicator. Perfectly suitable for home use, the Neuro Duo offers a powerful and portable option for personal PBM. The controllers that come with this set are dual-voltage and rechargeable.

    This device includes :

    • 1 Alpha Controller unit (10 Hz frequency)
    • 1 Gamma Controller unit (40 Hz frequency)
    • 1 Transcranial headset (containing four LED modules)
    • 1 Intranasal applicator
    • 1 Charger unit
  • The Vielight Neuro Gamma is a powerful brain photobiomodulation (PBM) device. It is one of two next-generation near infrared (NIR) wearable devices, suitable for use at home. The patented combination of transcranial and intranasal stimulation makes the Neuro Gamma ideal for comprehensive brain photobiomodulation, by simultaneously stimulating the ventral and cortical brain areas. Powerful yet simple, the Vielight Neuro Gamma features microchip-boosted transcranial LED diodes, which generate sufficient power to penetrate the skull (Link). Furthermore, the Neuro Gamma's refined form factor allows it to fit a wider variety of head shapes and sizes. At present, our engineering team is able to extract one of the highest amounts of power in the world from a near infrared LED source.

    Difference between the Alpha and Gamma

    • The Vielight Neuro Gamma's 40 Hz pulse rate correlates with EEG gamma brain oscillations, which has a stronger effect on memory and cognition enhancement. This pulse rate differs from the 10 Hz pulse rate of the Vielight Neuro Alpha, which has an overall effect on neuronal health.

    • Near-infrared light is nearly invisible to the naked eye, making the beam appear much dimmer than it actually is. The power density of the transcranial LED is 100 mW/cm2per diode. The power density of the intranasal LED is 25 mW/cm2.

    Please note that this device is not the same as the Neuro RX Gamma that is currently being used in our clinical trials. The RX Gamma is intended to be fully compliant with regulatory requirements for a medical device and will not be available without regulatory clearance. The “Neuro RX Gamma” is therefore a different product from the “Neuro Gamma".

  • Designed initially as an add-on for the Neuro, the Vielight X-Plus’ design and flexibility enables delivery of photobiomodulation (PBM) to a variety of areas not already covered by other Vielight devices. Engineered for versatility, it comes with a powerful 810 nm LED module (NIR) attached to a flexible stainless steel band. This modern design allows for easy delivery of near infrared (NIR) light to various brain areas (primarily posterior), as well as other body areas. Additionally, the X-Plus comes with its own 633 nm intranasal applicator for systemic photobiomodulation. The 633 nm wavelength of the intranasal applicator complements the Neuro's 810 nm wavelength.

  • The Vielight 633 Red is a compact personal photobiomodulation (PBM) device. Its cold LED 633nm red beam is ideal for systemic photobiomodulation via photonic diffusion through the nasal blood capillaries. The Vielight 633 Red and Vielight 655 Prime are comparable in efficacy.

    Why intranasal?

    The nasal cavity is rich with blood capillaries. There are more capillaries per cm2 than in most organs of the body. Five arteries connect to the nasal cavity, while the Little's area is a frequent site of nasal bleeding. Given the rich supply of blood and the thin, permeable membrane within the nasal cavity, the light can easily reach the blood. Thus, this area is well-suited for systemic photbiomodulation which via blood. This Vielight 633 Red device can be used in combination with the Vielight 810 : (Link) The scientific reasoning behind the difference between the 633 nm and 810 nm wavelengths can be found in this independent study : (Link
  • The Vielight 655 Prime is a compact personal photobiomodulation (PBM) device.

The diode's transparent high impact polycarbonate enclosure ensures quality and durability, turning this PBM device into a life-long investment.  
  • The Vielight 810 Infrared is engineered for gentle brain stimulation. This device complements the systemic effects of the Vielight 633 and 655. The 810 nm near-infrared wavelength is ideal for diffusing through the intranasal channel to reach the deep ventral brain areas. Note: The Vielight 810 and Vielight Neuro use different diode technology. The Vielight 810's intranasal power density is approximately 50% of the Vielight Neuro's intranasal power density.

    Why intranasal?

    The nasal cavity is a pathway to the ventral prefrontal cortex. The distance between the nasal bridge and the ventral prefrontal cortex is relatively short and permeable. Vielight intranasal devices combine solid state technology with intranasal diodes built from transparent high impact polycarbonate. The design ensures quality and durability, turning this purchase into a life-long investment.

    Note for users

    • Near-infrared photons are nearly invisible to the naked eye, making the beam appear much dimmer than it actually is. Additionally, the beam is pulsed at 10 Hz.
    • Sleepiness is a common side effect of using this device due to the pulse rate correlating with alpha brain waves and neuronal stimulation.
