At present, the lights in the light box are generally roller shutter lights. The lightfish led light bar explained that when installing, the back of the light bar can be temporarily fixed with double-sided tape, and then a few screws can be used. Installation is very simple. When installing, it should be noted that this kind of roller shutter light bar is generally at 12V or 24V voltage, which requires extra power supply, and cannot be directly connected with 220V power supply, so as to avoid lamp burning and other problems.
