All Vielight devices have been tested by TĆV 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 deviceās 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):Ā 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):Ā 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.
