• USE LAST RUN DATA refers to the data set used in the
last executed PBM session.
• USE CONTROLLER DATA refers to the data set of
parameters that are currently stored in the controller.

To create a new program with custom settings, please select set-up for one data block by pressing button single.

What is a single data block?
The data block is a set of parameters or settings, including frequency, power (density), time and module control settings.
When a gray dialog box (a) opens up, select the create new file option.
When the dialog box (b) opens up, give your settings a name and type it into the File name field.
You can also make notes for yourself by typing them into the Notes field.
Press save to save your custom settings into a file.
Later you will be able to retrieve and use that file with all your saved settings.

What is a group?
A group is a combination of data blocks which are custom programs that run in a predefined sequence.
More information about groups can be found further in this user guide. See the following section on CombiningData Sets Into Groups (A1).

You can create a group that contains up to 9 custom data blocks (custom files) which you saved in your library.
To create a group, select data block files (the files which you saved earlier) and place them within the sequence where you would like them to run in. Then, press save, to save your group settings as a group file.

Here are the steps to follow:
1. Select the stage (Stage 1, Stage 2, etc.)
2. Select the program to place into the stage.
3. Repeat this procedure for as many stages as you’d like to have in your tPBM group session, and save.
4. The dialog box (a) will open, asking you to update existing file or create new file.
5. Choose create new file.
6. From the files that you saved earlier, select which file you’d like to include in the group.
7. In the dialog box (b), give the file a name and save.

The Neuro Pro offers the ability to customize the settings for each transcranial LED module individually.

Identification of the Neuro Pro headset LED modules:
Front LED Module Set (3 LEDs):
(HFL) Hset front L — Headset front Left
(HFC) Hset front C — Headset front Centre
(HFR) Hset front R — Headset front Right
Middle LED Module Set (3 LEDs):
(HRL) Hset rear L — Headset rear Left
(HRC) Hset rear C — Headset rear Centre
(HRR) Hset rear R — Headset rear Right

The set module frequencies selection in the gray dialogue box (on the right) allows the user to set module frequency globally or individually via the Frequency menu.

You have two options for the Frequency settings:
1. The Set all option — covers all the modules globally (the top input cell shown on the opposite page). You can enter one value per setting and all the modules will accept that value.
2. The module specific set up option (the rest of the settings shown on the opposite page). You will have to enter specific values for each module.
NOTE: The upper frequency limit is 10,000 Hz.

Frequency sweep allows the user to specify the start frequency and the end frequency values for a tPBM session, while customizing the frequency step and step duration. The frequency step size refers to the number of Hz at which the light pulse frequency will increase during a tPBM session. This increase occurs in periods defined by the step duration.
The step duration refers to the value of time between step size increases.

To set a Frequency sweep:
Enter your preferred parameters in each of the four fields and press set (see screen to the right).
NOTE: In simple terms, frequency (Hz) references the number of times the light pulses per second. You cannot set a negative step size.

Set module power — enables the user to set the power density from 15% to 100%, globally or within each Neuro Pro module.

You have two options for the Module power set-up:
1. The Set all option — covers all the modules globally. You can enter one value for all modules.
2. The module specific set up option. Here you will have to enter specific values for each module.
NOTE: The maximum power density is currently limited to the following:
Headset modules ••••••••••••••••••••••••••••••••••• 100 mW/cm^2
Pro Module A •••••••••••••••••••••••••••••••••••••••••• 50 mW/cm^2
Nasal Applicator ••••••••••••••••••••••••••••••••••••• 50 mW/cm^2

Power sweep allows the user to specify the start power and the end power values for a tPBM session, while customizing the power step size and the step
The power step size refers to the % increase in the power of light intensity during a tPBM session. This increase occurs in periods defined by the step duration.

Power sweep setting enables the user to:
1. Set the start power and end power within each module. The range for the power sweep is from 15% to 100%
2. Set the power step size and step duration. The power step size ranges from 1% to 99%. The step duration ranges from 1 second to 999 seconds.
NOTE: The power step size refers to the gradual increase in power. You cannot set a negative power step size.

Control the phase (option A or B), the duty cycle, and select continuous light or keep it at the default pulsed light option.

You have two options for the Module control:
1. The Set all option — covers all the modules globally (the top input cell shown on the opposite page). You can enter one value per setting and all the modules will accept that value.
2. The module specific set up option (the rest of the settings shown on the opposite page). You will have to enter specific values for each module.

What is Phase angle? (gray dialog box on the right)
The phase angle determines whether the Neuro Pro modules will pulse in-phase or out-of-phase with each other (i.e. synchronously or asynchronously).

There are two phase angles to choose from, (A) and (B).
For example, setting all the front modules to (A) and all the rear modules to (B) will make the front and back modules pulse out-of-phase or asynchronously.
Similarly, any two (or more) modules can be set to pulse synchronously or asynchronously.

What is duty cycle?

  • The duty-cycle refers to the total duration of time the light stays on over the duration of the PBM session.
  • The duty cycle is fixed at 50%.
  • The module control has three options: 50%, ON or OFF.
  • When set to 50% the light has a 50% duty cycle.
  • When set to ON, the light is continuous (not pulsing).
  • When set to OFF the light is turned off.

EXAMPLE: When the duty cycle is set to 50%, light energy will be emitted only 50% of the time.

Frequency, expressed in Hz, indicates the number of pulses per second.

Duty cycle, expressed in %, refers to the percentage of time that the light energy is emitted during the session.

EXAMPLE: A setting with frequency of 10 Hz and a 50% duty cycle refers to 10 pulses of light every 1 second, and the light staying on 50% of the time of the total tPBM session time. If a tPBM session lasts 20 min with a duty cycle of 50%, it means that the total active tPBM time during the session is 10 min (20×0.5).

If the connection between the Neuro Pro app and the controller is lost during the session, the controller will continue to run within the given settings.
Press the reconnect button to re-establish the connection between the controller and the app.

Questions & Answers

What is near infrared (NIR) light?
Near infrared light is electromagnetic radiation (with the wave length of 700-1400 nm) within the electromagnetic spectrum. It is mostly invisible to the naked eye, even if emitted with a high power density.

Do the units come with instructions?
Yes, there is a manual provided within every device packaging. Also, there are visual instructions available through the following video links:

  1. Vielight Neuro (older model) – Link
  2. Vielight intranasal devices – Link

What conditions do the intranasal devices help with?
Please note that we recognize our devices as still experimental. While the data from our pilot study in collaboration with researchers from Harvard Medical School and Boston University School of Medicine was statistically significant, we do not claim anything beyond a theoretical perspective. We’re currently conducting clinical trials with recognized research authorities to improve on the efficacy of our devices. Thus, we partner in research with Baycrest Hospital (Canada), St Michael’s Hospital (Canada) and the Veterans Affairs of the United States (USA).

How soon can I see improvements?
This varies on an individual basis. Some users have reported changes within a week, however, some have taken much longer to notice improvements in their general wellness.

I am going to share my device with other people. Can I cover the applicator with a plastic cap or other materials?No, this would reduce the coherency of the light source and will reduce its effectiveness.

Will the intranasal devices interfere with my pacemaker?
To date, there are no reported incidences of interference with pacemakers.

Can I carry and use Vielight devices on a plane?
Yes, you can.

Can I use Vielight devices on my pets?
Yes, you can. The Pocket Miracle ( works best for external applications.

Where are Vielight devices made?
Components come from different parts of the world. They are assembled in the USA and Canada.

What happens if I see no results?
In the rare circumstance that you do not see any results – we offer a 6-month satisfaction guarantee for an 80% refund of the purchase price. You should contact the place you bought it from to process this refund.

PLEASE NOTE: As of 1st March 2017 – our customer support, satisfaction guarantee and product warranty will not apply to devices sold through unauthorized channels, such as Amazon and eBay.

How long does each session last? 
The Vielight intranasal units are auto-timed for 25 minutes, while the Neuro is timed for 20 minutes.

How often should I use my Vielight devices? 
We recommend using the Vielight standalone intranasal units twice every day, once in the morning and once at night.
The Neuro Alpha|Gamma’s suggested usage is once every 2 days. For severe mental acuity issues, more frequent usage is mentioned in clinical trials and research studies related to the devices – Link

Can I use a different device in each nostril at the same time?
Yes, you can. The Vielight 633/655 in one nostril and Vielight 810 in the other to target both systems. This is because electromagnetic radiation of different wavelengths does not mix.

As an example, a research department in the Veterans Affairs uses both devices at the same time –Link

Does it matter which nostril I use?
It does not matter which nostril is used. However, users with sinus issues and/or eye issues may interchange nostrils to target both sinuses, optic nerves and both eyeballs.

Can children use this?
Yes. However, cut time interval down to 5-10 minutes as a start then gradually extend the time. If headaches occur, reduce the time frame back down.

Can I share a unit with my partner/spouse?
Yes, you can. It is recommended that you clean the nasal applicator with a swab of alcohol between each consequent use. If you are not comfortable with sharing, you can always purchase a separate nose applicator.

What is the difference between the Vielight 810 and the Neuro Alpha/Gamma?
– The Vielight 810 is a near infrared (NIR) intranasal-only device that was engineered for everyday use.
– The Neuro Alpha/Gamma were designed to deliver more powerful and comprehensive stimulation. It utilizes an infrared transcranial headset combined with an intranasal Neuro applicator. It has a significantly higher power density than the Vielight 810. Its recommended usage is once per day to address above average mental acuity declination and once every other day, for users with normal mental acuity. Protocols can be found here Link.

What is the difference between the Neuro Alpha and Neuro Gamma?
The 10 Alpha Hz model is what we have clinical data with in our pilot study –

However, the 40 Hz Gamma model is what we’re using in our latest clinical trials – /

Please note that the technologies are still being studied in clinical trials are not approved by any national regulatory body for the treatment of specific medical conditions.

What’s the difference between the Vielight 655 and Vielight 633?
The Vielight 655 utilizes a low level laser diode while the Vielight 633 utilizes a LED. Lasers have a longer research history than LEDs. However, the usage of LEDs is gaining popularity in the field of photobiomodulation.

I have a Vielight 810 but I want the Neuro. What can I do?
If it is less than 6 months since you bought the 810, you can send it back for an 80% refund, and apply the proceeds against the purchase of a Neuro.

Which of the 3 intranasal units is the best?
No unit is the best. Pick the model that best suits what you are trying to address. The Vielight 633/655 emphasize the body, the immune system and cardiovascular issues. The Vielight 810 and the Neuro Alpha/Gamma emphasize the brain.

I do not see any light at the 810 nose applicator. Is this normal?
Light at 810nm is near invisible. Sometimes people mistakenly think the applicator is faulty as the light can appear to be dimming or even invisible when viewed at certain angles. However, the power density is deceptively stronger than what it appears to be.

My device is faulty. Where can I send it for repairs or replacement?
First, give us a call at 1-877-355-8012 (North America) or 1-647-865-2803 (International) and we will trouble shoot the problem with you. If your device is faulty, return it to your supplier or return it to us, if it was purchased directly from us. If it is still under our one-year warranty, we will replace it.

I have been using my intranasal for some time. Now there is no light at the applicator. What is wrong?
There are two reasons why your applicator has not light.

– The first reason is the device is switched on without the applicator. To rectify this, switch the power off, attach the cable to the control unit and then switch the power on again.
– If there is still no light, check for a persistent green light at APP Fault. If there is a green light there, the applicator is faulty. The applicator will be replaced by your supplier if it is still under warranty. Otherwise they can be purchased from

How long do the diodes last?
Our intranasal diodes are built from transparent high impact polycarbonate. They are built to last for years and are covered by a year-long manufacturer’s warranty.

What batteries do your devices use?
– The 633, 655 and 810 Vielight devices use 1.5 V AA batteries
– The Neuro is rechargeable (charging unit is provided)

Do Vielight devices have Health Canada approval?
No, our devices are not yet approved to treat any medical conditions and are only marketed as general wellness devices. All Vielight devices have been independently TÜV certified as safe for consumer use.

Do Vielight devices have FDA approval?
No, at present. The FDA have categorized our devices as low-risk general wellness devices in accordance to the FDA’s draft on “General Wellness: Policy on Low Risk Devices” – dated January 20, 2015. All Vielight devices have been independently TÜV certified as safe for consumer use.

Are these covered by medical insurance?
No, they are not unless your insurance plan covers wellness devices.

What payment methods do you accept?
For now, we accept only Visa, MasterCard and Paypal.

What are your international shipping fees?
