Well-known domestic LED manufacturers include Jiangmen Heshan Yuyin, Zhongshan Future, Dongguan Qinshang and Jiangmen Katie. The lingering sound is famous, but its relative price is relatively high. Weilai mainly produces rainbow tubes, and the price of Qin is lower than that of Yu Yin. If you want to use mid-range products, Jiangmen Katie is more suitable, and the price and quality are no problem.
