- Look at product packaging and trademarks
This is the most simple and intuitive way to distinguish. The outer package of genuine LED lights shall be marked with information such as rated voltage, voltage range, rated power, etc., as well as brand trademark and relevant certification mark. The trademark on the outer package of the genuine LED light has good printing quality, clear font, and is not easy to fall off. Even if it is wiped with a soft wet cloth, the trademark is still legible. The trademark printing quality of fake and inferior products is poor, and the font is fuzzy. The trademark of some products can be erased with wet cloth. In addition, there are some inferior products on the outer packaging without printed trademarks and related certification marks.
- Look at the light tube appearance
The genuine LED light uses three primary color tubes, and the color of the tubes is white. After being covered by hand, the color will look white. When purchasing, consumers can put multiple LED lights together for comparison. The products with better consistency of light shape and size are generally mass-produced products with guaranteed quality. In addition, it is also necessary to check whether the appearance of LED light has cracks and looseness, and whether the interface has been pried. If so, it indicates that it is a poor product. The genuine LED light will not be loose or crooked during installation and disassembly.
Consumers can also distinguish the quality of LED light by its shell material. The plastic shell of genuine LED light is made of flame-retardant material with rough texture, similar to frosted glass. The inferior products are made of ordinary plastics with smooth and glossy surface, which are easy to deform and burn.
- Look at the temperature at work
In the working state, the temperature of the genuine LED light will not be too high, which can be contacted by hand. If the temperature of the purchased product rises obviously at work, it indicates that there is a problem with its quality. In addition, if the LED light flickers, it also indicates that there is a quality problem.
- See electromagnetic interference
In China, electromagnetic compatibility is an important index to check whether the electrical products are qualified. Therefore, consumers can check whether there are relevant marks passing the test on the outer package of LED lights when they buy them.
