THE EMR-TEK STANDARD
BUILT TO PREFORM
COB chip technology. Meanwell-engineered drivers. Red (660nm) + Near-Infrared (850nm). More irradiance and longer LED life than standard SMD builds — verified output on every device before it ships.
EVERY SPEC PUBLISHED
Wavelengths, irradiance, flicker, and EMF — third-party tested and fully disclosed. Nothing hidden behind "clinical-grade" or "medical-grade." If we printed it on the page, we hit it on the bench.
