What is the meaning of the SDCM specification ？

SDCM serves as a key quality control standard during flexible strip manufacturing.  Flexible strips with low SDCM values usually indicate rigorous screening and advanced manufacturing processes, classifying them as high-end products. Our products are < 3 SDCM. Strips with SDCM ≤ 3 exhibit nearly imperceptible color variation, delivering consistent, soft illumination without visual discomfort. Low SDCM strips offer superior initial color stability, ensuring minimal color change during long-term use and extending service life.
