Empowering TBI Research

There’s no required waiting period. In published research, Vielight devices have been used anywhere from weeks to years after a head impact. The University of Utah studies recruited former athletes long past their playing careers.

Timing is still worth discussing with your healthcare provider, especially if your injury is recent. We don’t recommend our devices if you have active brain bleeds or a history of seizures.

The Neuro devices (Pro, Duo, Gamma, Alpha, and the Duo + Vagus combination) are timed for 20 minutes. The MIP is timed for 25 minutes.

You can use your Vielight device between every other day to six days a week, depending on your needs and health. For our Neuro devices, our general recommendations are:

• Pro, Duo & Duo + Vagus: Once daily, alternate between Alpha and Gamma.
• Gamma: Once daily, in the morning or early afternoon.
• Alpha: Once daily, before bed.

All Vielight devices have been tested by TÜV Rheinland, an accredited independent testing body, to two internationally recognized safety standards: IEC 62471 for photobiological safety, and EN 62368-1 for general product safety. Together they cover both the light our devices emit and the electronics that produce it.

How is the light itself evaluated?


IEC 62471 is the international benchmark for the safety of light emitting products. It measures a device’s actual optical output against exposure limits for the eyes and skin, established by the International Commission on Non-Ionizing Radiation Protection. Vielight devices have been certified safe.

• Electrical & Thermal Safety (EN 62368-1:2014): Tested under the international safety standard for electronic, IT, and communication equipment. This certification ensures comprehensive protection against electrical shocks, overcharging, mechanical hazards, and excessive thermal output (overheating).
• Optical & Photobiological Safety (IEC 62471): Tested for light and optical radiation safety. This standard verifies that our high-powered LED and Near-Infrared (NIR) emissions operate within recognized exposure thresholds, ensuring safe use for skin and eye exposure.

And the device electronics?

EN 62368-1 is the modern safety standard for consumer electronics, the same one applied to laptops, audio equipment, and communications hardware. It takes an engineering-first approach, identifying the energy a product uses and verifying that appropriate safeguards are designed around it.

What does safety testing tell me, and what does it not?

Safety testing confirms that a device is engineered and manufactured to recognized international benchmarks. It is a separate matter from regulatory clearance for a specific medical use. Vielight devices are general wellness products, and are not intended to diagnose, treat, cure, or prevent any disease or medical condition, including traumatic brain injury, concussion, or CTE.

Yes. Vielight devices can be used on their own or alongside other therapies, with no reported interactions. If you’re already working with a physician, physiotherapist, or neuropsychologist, it’s worth telling them you’ve started, mostly so someone with your full history is tracking your progress alongside you.

40 Hz Gamma, delivered through the combined intranasal and transcranial pathway. It’s the mode used across the published research, and it’s a preset on both the Neuro Duo 4 and the Neuro Pro 2.

Two things: how much of the brain the light reaches, and how much of it arrives.

Devices that send light in through the top of the head reach only the top half of the brain. Vielight reaches the whole brain, using two routes at once in a patented approach called itPBM (intranasal-transcranial photobiomodulation). Most VIE-LEDs sit on the scalp, and a small light sits just inside the nose, a much shorter path to the deeper areas tied to memory and emotion. No other helmet can take that route.

The second difference is how much light arrives. Independent labs measured Vielight’s scalp modules at more than ten times the near-infrared light you would get standing in the sun. The two helmets tested alongside came in below sunlight, at roughly a quarter and a sixth of it. Vielight’s VIE-LEDs are curved so they part the hair and sit against the scalp, because hair scatters light before it reaches bone.
