This device includes:

  • 1 Transcranial headset
  • 1 Intranasal applicator
  • 1 Charger unit
  • 1 Carry case
  • 1 Storage pouch
  • 1 Silicon sleeve


As a powerful and well-researched transcranial brain photobiomodulation (tPBM) device with intranasal technology, the Vielight Neuro Duo is a next-generation brain stimulation device that’s safe, effective and easy to use. Our patented transcranial-intranasal technology offers a unique and powerful advantage for comprehensive brain stimulation of the Default Mode Network.

The Neuro Duo transmits pulsed near-infrared (NIR) energy through the cranium, activating a process known as photobiomodulation. Through engineering and microchip technology, we are able to extract one of the highest amounts of power from a near-infrared LED energy source without generating heat.

Gamma (40Hz): focus, information processing, memory improvement, energizing.
Alpha (10 Hz): mindfulness, learning, relaxation, sleep improvement.

Vielight Neuro FAQ

What wavelength does the Vielight Neuro emit?
The Vielight Neuro emits pulsed 810nm NIR energy to enable brain stimulation through the photobiomodulation process.

Why the 810nm wavelength?
The 810nm wavelength has the deepest penetration through tissue and bone, enabling photonic transmission to neuronal mitochondria.

What is the difference between the Duo, Gamma and Alpha models?
The Gamma model pulses NIR light energy at 40 Hz, which has a neuromodulating effect on Gamma neural oscillations.
Effects are an increase of focus, information processing, memory improvement, energizing.

The Alpha model pulses NIR light energy at 10 Hz. This frequency is similar to neural alpha waves. Theoretical brain stimulation effects on alpha waves have a correlation with the brain’s resting state, offering support for mindfulness, learning, relaxation, sleep improvement.

The Duo makes both of these pulse rates available to you – having both pulse rates brings the most benefits.

How much power do your brain photobiomodulation devices generate?
Our brain photobiomodulation devices generate sufficient power to penetrate the skull and produce statistically significant results in independent research studies.

What is the recommended usage?
The general recommended usage is to use once every other day before experimenting with more frequent usage, not exceeding once per day. For more serious cognitive impairment, the recommendation is once per day, six days a week. Please note these recommendations are theoretical and anecdotal.

  1. Edward Rimes (verified owner)

    As a biohacker, I am always looking for ways to improve my mental performance and relax. And while I do not know a lot about brain stimulation devices, I am really happy with the results from Neuro Duo. I can definitely tell that it made my creativity better, helped me to process information quicker and overall boosted my performance. It has been a lifesaver for me these past few weeks at work!

  2. Monkey Box (verified owner)

    I’m an engineering grad student and I use both modes to help with my studies and stress management daily, it’s useful. I wish this device was cheaper though. My dad, being a doctor, saw the value in this and paid half.

  3. mianhey (verified owner)

    ok some preface, I’m not young and I used to be a teacher. not sure if it’s placebo but I noticed that I’m recalling names and words faster than before. my speech started slurring after I hit 60 but now I feel like I’m back to being eloquent. either way, I’m happy that this device is convenient and easy to use, my son helped me set it up but using it is a breeze while I watch tv

  4. Earth Lover (verified owner)

    OK a few things. 1) This is a very powerful device that works better for me than all the other brain stimulation devices I’ve tried, especially tDCS. 2) The two modes Gamma and Alpha are useful but I feel more of an effect from Gamma than I do from Alpha. 3) You don’t have to follow Vielight’s recommendation of once per day, I use this device twice a day. 4) I’m only giving this 4 stars because I expected higher quality materials for the price.

  5. Vielight User 180 (verified owner)

    A useful device for people that care about the health of their brain. I’ve always been sensitive to changes within my cognition as a meditator and I can tell that this device works in a positive way.
    However, the form factor is outdated and not stylish. I wish Vielight would improve the appearance of their products.

  6. Dulce (verified owner)

    I bought this device for my elderly grandfather and I have seen an improvement in his memory and gait. He uses the Gamma mode. My grandmother is healthy but uses it for her brain health. Go grans!
    We’ve had it for 5 years now and it’s still functioning well. Only the nasal cord needed to be replaced last year.
    Thanks Vielight!

  7. ethan howell (verified owner)

    I bought the vielight neuro duo for general brain health improvement, and I use gamma in the morning and alpha in the evening for brain modulation. Both modes work well.

  8. Fandango (verified owner)

    As a professional musician that works in the movie industry, I am always looking for ways to improve my mental performance and relax. And while I do not know a lot about brain stimulation devices, I am really happy with the results from Neuro Duo. I can definitely tell that it made my creativity better, helped me to process information quicker and overall boosted my performance. It has become an integral part of my lifestyle over h=the past year.

    Photobiomodulation is a form of therapy that I’ve followed for awhile. I’ve used photobiomodulation all the way back when it was still known as low level light therapy. Speaking from years of running a vet clinic in a busy town, I’ve used lasers to treat animal wounds with great success. I definitely believe it has an effect on the brain and mitochondria if the light energy is able to get through the bone and skin. I like how Vielight is able to produce 100 mW/cm^2 from LEDs, that’s quite remarkable given that the competition only churns out 10-15 mW at best. 4/5 stars because I think it should be cheaper.

  10. Jackie Delap (verified owner)

    I received an invitation by email to write a review, so here it is. This device is on the pricier side but I share it with all my family members, so it is well worth it. There are 5 people in my family. I use the Gamma mode for my mother’s memory issues and the Alpha mode for my father, who has anger issues from a TBI he suffered a decade ago. My two brothers use it as well.
    If you intend on sharing this device, follow Vielight’s advice and sterilize the nasal applicator between uses.

  11. Pierre Maere (verified owner)

    I purchased the Neuro Duo and it’s a great investment so far. I have seen an improvement in my energy levels and cognitive abilities since using the device. I accidentally damage dhte nasal probe but vielight replaced it while it wa sstill under warranty. Merci Vielight!

  12. Miles Kelley (verified owner)

    I recently bought the Vielight Neuro for my father, who has been suffering from memory loss due to age. I was skeptical at first, but after only a few weeks of use, I could already see an improvement in his cognitive abilities. He is now able to remember things more easily and recall information quickly. The Vielight Neuro is an excellent device and totally worth the price tag!

  13. Alaia Fyke (verified owner)

    This device worked for my father’s mental clarity but I’m only giving it 3 stars because it is very expensive. I understand that Vielight funds a lot of research but they should find a way to make it cheaper.

  14. john michaud (verified owner)

    Un excellent appareil pour la stimulation cérébrale. Cependant, l’expédition de l’appareil en Belgique coûte cher, $150

  15. James ZIELINSKI (verified owner)

    Owning my own brain photobiomodulation device has been on my radar for awhile after loaning my friend’s Vielight Gamma for a week. I decided to step up and get the Alpha mode too. I definitely feel the difference in brain modulating effects that it brings from an energizing or calming perspective.

  16. John the Chiropractor (verified owner)

    I recently started using the Neuro Duo in my chiropractic office and it has been a great addition for my practice. Its easy-to-use interface and non-invasive stimulation have proven to be effective but the comfort level varies from client to client. Hence. only the 4 stars. If vielight could design a more comfortable and less scary looking variant in the future, i’d be more comfortable recommending this to ANYONE. Someone mentioned they think they’re being assimilated as a Borg from Star Trek. The inherent safety of the LEDs make it a great and safe add on to any office’s toolbox. Highly recommend by signing up for their reseller’s program if you’re a practitioner.

  17. veraaa01 (verified owner)

    An interesting device, can’t say I believed in brain photobiomodulation until I tried it for myself. I didn’t feel any effects for a few weeks but after, I’ve noticed much better mental clarity and I’m sleeping better at night.
    Only 4 stars because I feel like the device could be made to look sleeker for the price point. It looks cool but weird.
