Matters needing attention : - When installing and using, please do not pull hard, and fix it, and do not swing back and forth, so as not to cause the lights of the lantern to break, resulting in the lights not turning on. - When using it outdoors, please place the head of the product controller down and fix it to prolong the service life. It is best to turn it off when it rains, and then turn it on after a period of rain. - As the lantern is made up of many wires, and the voltage and current resistance of each set of lanterns is designed as a whole, each line and the lamp beads complement each other, so it must not be cut or connected without authorization.
