An independent comparison review of power density/irradiance, commissioned by the PBM Foundation, was conducted by Optronic Lab on the Vielight Neuro 3, Neuronic Neuradiant, and Suyzeko NIR Helmet. Utilizing a calibrated OL 770 VIS/NIR Spectroradiometer, the study assessed irradiance as received by a user at the scalp contact points, with devices set at maximum intensity.
Findings reveal the Vielight Neuro, measured at 200-300 mW/cm2, emits a surface power density 30-50 times higher than the Neuradiant. The Neuronic Neuradiant, originating from Suyzeko's helmet platform, emits an irradiance measured at 6mW/cm2.
Using sunlight’s irradiance (100mW/cm2) as a reference, the Vielight Neuro’s power density surpasses sunlight by 200-300%, whereas the Neuronic Neuradiant and Suyzeko helmet achieve only about 5-6% of sunlight's power density.
This report underscores the importance of independent testing and standardization by accredited bodies to ensure manufacturers declare true irradiance numbers.
