1. Determine the position of the lamp, punch holes, install the lamp body and buckle, and connect them in parallel every six meters. The rated voltage is 220V, which can be directly connected to the mains, otherwise a controller is needed.
2. The installation angle of the external wall is downward, otherwise it will cause light pollution. If the installation angle cannot be downward, you can choose hidden installation. Hidden installation requires a manual screwdriver, with the lamp slot facing up. Clean the lamp trough every two months. Pay attention to the waterproof of the lamp trough in rainy days.
