Compared with ordinary lamps and lanterns, led lamps have the characteristics of energy saving, environmental protection, long life, and high luminous efficiency. They can both serve as both decorative and lighting effects, and are therefore favored by more consumers. However, the LED lamp market is mixed, and the quality varies greatly. It is not so easy for consumers who don’t know much about the led lights to choose the right one. The following Xiaobian teach you a few ways to identify the quality of led lights, I hope to help you choose the right led lights.
| First, look at packaging and trademarks |
The national mandatory requirements LED lighting manufacturer's products on the packaging marked the following: rated voltage, voltage range, rated power, rated frequency. Generally speaking, the trademark of high-quality products is of good quality and printed with clear characters and is not easy to fall off. Wipe with soft and damp cloth, the mark is clearly legible, it is not easy to wipe off, and there are manufacturers' trademarks and related certification marks. Fake and shoddy products have poor print quality, fuzzy fonts, and are easily erased. There are no manufacturer's trademarks and related certification marks.
| Second, look at the appearance of led lamp |
The real LED energy-saving lamp is a three-color tube, white tube, covered by hand to see, more white. In addition, from the lamp point of view, more than one lamp can be put together to compare the better shape and size of the lamp tube are mostly machine bending forming, mostly large-scale production of products. Product consistency is good, quality is easier to ensure, and interchangeability during maintenance is better. Of course, there must not be cracks, looseness, and traces of cracks in the interface. In the process of installation and dismantling, there should be no loosening of the lamp head and a smashing phenomenon.
The plastic shell of the lamp must be selected as the kind of engineering plastic flame retardant. Ordinary plastics are easily deformed and flammable, and are prohibited from being used in the production of energy-saving lamps. From the surface, it is easy to distinguish between the two. The latter surface is smooth and shiny, and the former has a frosted glass-like texture.
| Third, see the drive |
The life of the general led is not 50,000 hours that the manufacturer says, but now the cross-flow driving through the European Union authentication on the market can basically reach 20,000 hours. Since the LED lighting level products were only available for 2 to 3 years, it is impossible to know that it can be driven for 5 to 10 years without being bad and not declining, so the general manufacturers will have a two-year warranty.
| Fourth, see the start performance |
LED energy-saving lamps start with two characteristics: First, the higher the temperature is easier to start; Second, the light is turned off, will not flash. In addition, it is worth mentioning that many LED energy-saving lamps are very dark, which is unfavorable for lamp life. LED energy-saving lamps should have power circuits and PCB boards inside.
