When inspecting lamps, the first step is to check the markings on the lamps, such as trademark, model, rated voltage, rated power, etc., to determine whether they comply with public usage standards. Marking safety is a fundamental requirement in the safety performance of lighting fixtures, with rated power being particularly important. For example, if a lighting fixture is designed with a rated power of 40 watts and is not marked with a rated power, users are likely to install a 60 watt or 100 watt bulb, which may cause shell deformation, insulation damage, or even electric shock, and may also cause a fire. In addition, the standard stipulates that the minimum cross-sectional area of wires used on lighting fixtures is 0.5 square millimeters. Some manufacturers, in order to reduce costs, use wires with a cross-sectional area less than 0.5 square millimeters on their products, which may cause the wires to burn, and the insulation layer to burn out and cause short circuits, posing a danger. During inspection, you can check the markings printed on the insulation layer outside the wires on the lamp
