How to judge the quality of the led light string？
When it comes to LED string lights for motif displays, do you know how to evaluate their quality? Since they are used outdoors, they must be waterproof (IP67-rated), moisture-resistant, cold-resistant, and UV-resistant. First, the wiring must consist of VDE-certified rubber cables (specifically, H03RN-H-F type with 1 x 0.5mm² copper conductors). Second, the rectifier bridge must be waterproofed with potting compound. Third, the LEDs themselves must be of high quality, offering a long lifespan and minimal light decay. Meeting these requirements ensures consistent, reliable quality. wendadeco have this kind IP67 waterproof LED light strings
