How do Sunsred ensure that different batches of LED beauty masks maintain stability in wavelength consistency and irradiance levels?

Relying on rigorous scientific testing and deep technical accumulation, Sunsred always maintains industry-leading optical performance consistency!

We take multiple key measures to ensure the optical performance of every batch is precise and stable:

Rigorous Batch-by-Batch Testing: Every production batch must undergo precise integrating sphere testing and optical pointer testing.

Precise Wavelength Control: We precisely measure every wavelength, ensuring its accuracy is strictly controlled within a ±5nm range, and can provide detailed test reports upon request. 

Excellent Consistency Record: In multiple audits during 2024, we consistently maintained the optical performance deviation between batches at an extremely low level of <1%.

Strong Patent Technology Support: Behind this excellent consistency lies the solid support provided by our 30+ LED core technology patents.
