When faced with LED lights with many brands and different prices, many consumers neither know how to buy them, nor how to distinguish the quality of them. There are 4 main points to pay attention to when purchasing LED lights.
1. Look at product packaging and trademarks
This is a simple and intuitive method of identification. The outer packaging of genuine LED lights should be marked with information such as rated voltage, voltage range, and rated power, as well as brand trademarks and related certification marks. The printing quality of the trademark on the outer packaging of the genuine LED lamp is good, the font is clear, and it is not easy to fall off. Even if it is wiped with a soft damp cloth, the trademark is still legible. The trademark printing quality of counterfeit and inferior products is poor, and the fonts are blurred, and the trademarks of some products can be erased with a damp cloth. In addition, there are no printed trademarks and related certification marks on the outer packaging of some inferior products.
2. Look at the appearance of the lamp
Genuine LED lights use three-primary color tubes, and the color of the tube is whiter. After covering it with your hands, the color will look whiter. When purchasing, consumers can put multiple LED lights together for comparison. Products with better tube shape and size are generally mass-produced products, and the quality is mostly guaranteed. In addition, it is necessary to check whether there are cracks or looseness in the appearance of the LED light, and observe whether there are traces of prying over the interface. If there is, it means that it is a low-quality product. Genuine LED lights will not be loose or tilted during installation and disassembly.
Consumers can also distinguish the quality of the LED lamp by its shell material. The plastic shell of the genuine LED lamp is made of flame-retardant material, which has a rough texture, similar to frosted glass. Inferior products are made of ordinary plastics with smooth and shiny surfaces. Such materials are easily deformed and flammable.
3. Look at the temperature at work
In the working state, the temperature of the genuine LED lamp will not be too high and it can be touched by hand. If the purchased product heats up significantly during work, it means 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. Look at electromagnetic interference
In our country, electromagnetic compatibility is an important indicator for assessing whether electrical products are qualified. Therefore, consumers can check whether there is a relevant mark that passes the test on the outer packaging when purchasing LED lights. At the time of purchase, consumers can use medium and short wave radios for testing. Place the radio near the LED light after power-on and observe the noise from the radio. The lower the noise, the better the electromagnetic compatibility of the product.
