- Look at product packaging and trademarks
This is the simplest and most intuitive method of identification. The packaging of genuine LED lights should be marked with information such as rated voltage, voltage range, rated power, etc., as well as brand trademarks and related certification marks. The printing quality of the trademark on the outer packaging of the genuine LED light is better, 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 printing quality of the trademarks of the inferior and inferior products is poor, the fonts are blurred, and the trademarks of some products can be erased with a damp cloth. In addition, there are some inferior products with no printed trademarks or related certification marks on the outer packaging.
- Look at the appearance of the light
Genuine LED lights use three primary color tubes, and the color of the tube is whiter. After covering with your hand, the color will look whiter. When buying, consumers can put multiple LED lights together for comparison. The products with better tube shape and size consistency are generally mass-produced products, and the quality is mostly guaranteed. In addition, the appearance of the LED light should be checked for cracks and looseness, and the interface should be observed for signs of being pryed, and if so, it is a poor quality product. Genuine LED lights will not loosen or tilt their heads during installation and disassembly.
Consumers can also distinguish the quality of the LED light by its shell material. The plastic shell of the genuine LED light uses a flame retardant material, which has a rough texture, similar to frosted glass. Inferior products are made of ordinary plastics with smooth and shiny surfaces. These materials have the characteristics of easy deformation and flammability.
- See the temperature at work
In the working state, the temperature of the genuine LED light will not be too high, and can be touched by hand. If the purchased product heats up significantly during work, it indicates that there is a problem with its quality. In addition, if the light of the LED light flashes, it also indicates that there is a problem with its quality.
- See 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 on their outer packaging that passes the test when purchasing LED lights.
