1. Look at product packaging and trademarks

The outer packaging of a good-quality LED integrated light source module should be marked with information such as rated voltage, voltage range, and rated power, as well as brand trademarks and related certification marks. The logo printed on the outer packaging of the LED lamp of good quality is of good quality, with clear fonts and not easy to fall off. Even if it is wiped with a soft damp cloth, the logo 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

Good quality 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 consistency 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 lamp, and observe whether there are traces of prying on the interface. If there is, it means that it is a low-quality product. LED lights of good quality 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 a good-quality LED lamp is made of flame-retardant material, and the texture is rough, 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

Under working conditions, the temperature of a good-quality LED integrated light source module will not be too high and 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 the electromagnetic interference

In my 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.
