LED Light Therapy Mask OEM: Wavelength and QC
What to verify when sourcing an LED light therapy mask for OEM: wavelength accuracy, irradiance and the QC that keeps batches consistent.
An LED light therapy mask OEM order should specify the wavelengths (commonly 630/660 nm red and 850 nm near-infrared) and the tolerance.
Irradiance at skin distance, not the LED count, is what decides whether the mask actually delivers a useful dose.
Ask the factory for a spectral report per batch, because LED bins drift and QC is the only thing that keeps output steady.
Mask fit and the light seal around the eyes affect both comfort and results, so evaluate the physical design, not just the board.
A serious LED mask OEM also confirms the photobiological safety file (IEC 62471) for the wavelengths it ships.
