Teach you to easily distinguish the quality of led lamps, mainly reflected in the following four points:
1, see product packaging and trademarks
This is the easiest and intuitive way to distinguish. The outer packaging of genuine led lights should be marked with information such as rated voltage, voltage range, rated power, as well as brand trademarks and related certification marks. The quality of the printed logo on the outer packaging of genuine led lamps is better, the font is clear, and it is not easy to fall off. The quality of trademark printing of counterfeit and inferior products is poor, and the fonts are blurred. Some products' trademarks can be erased with a wet cloth. In addition, there are some inferior products with no printed trademarks and related certification marks on the outer packaging.
2, look at the appearance of the tube
The authentic led light uses a three-primary color tube, and the color of the tube is whiter. When it is covered by hands, the color will look whiter. When purchasing, consumers can compare multiple led lights together. The products with good shape and size consistency are generally mass-produced products, and the quality is mostly guaranteed. In addition, it is also necessary to see whether the appearance of the led lamp is cracked or loose, and observe whether the interface has been traced. If it is, it indicates that it is a poor quality product. Genuine led lights do not appear loose or tilted during installation and removal.
Consumers can also distinguish the quality of the led light by the shell material. The plastic shell of genuine led lights uses flame retardant materials, which have a rough texture, similar to frosted glass. Inferior products are made of ordinary plastic with smooth and shiny surfaces. Such materials are easy to deform and flammable.
3, look at the temperature at work
Under working condition, the temperature of genuine led lamps will not be too high, and it can be touched by hand. If the temperature of the purchased product increases significantly during work, it indicates that there is a problem with its quality. In addition, if the led light flashes, it also indicates that there is a problem with its quality.
4, see the situation of electromagnetic interference
In China, electromagnetic compatibility is an important indicator for assessing the eligibility of electrical products. Therefore, consumers can check whether the outer packaging has the relevant mark that passes the test when purchasing led lights.
