Certifications in Europe and America are more authentic. The forming of modular LED will accelerate the pace of replacing traditional lighting products, and it will at the same time promote simplification of standards. The modular LED lights are good at replacing and lowering maintenance cost. Therefore, more and more manufacturers are working on modular LED products.
