What is Vie-LED® Technology? The Importance of Irradiance

At the heart of Vielight’s innovation lies a proprietary engineering breakthrough: Vie-LED® technology. Designed specifically for transcranial and intranasal photobiomodulation (PBM), Vie-LED is not just another light-emitting diode system. It’s a meticulously optimized delivery mechanism that enables high irradiance output with minimal heat generation, ensuring both therapeutic potency and user safety. High Irradiance, Minimal [...]

Irradiance is Power: The Key to Effective Brain Photobiomodulation

In brain photobiomodulation, near-infrared (NIR) light within the 810–1100 nm wavelength range offers beneficial cellular effects and deep tissue penetration. However, if the wavelength is optimal but the irradiance (surface power density) is too weak, penetration will be minimal or nonexistent. The two most critical factors determining the efficacy of this therapy are irradiance [...]
