How to distinguish the advantages and disadvantages of LED explosion-proof lights

When faced with LED explosion-proof lights with many brands and different prices, many consumers neither know how to buy them nor how to distinguish their quality. In this regard, industry insiders have made a four-point summary to help consumers distinguish.
Look at the product packaging box trademark:
The outer packaging of genuine LEDs should be marked with information such as rated voltage, voltage range, and rated power, as well as brand trademarks and related certification standards. 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 clear and defensible. The trademark printing quality of counterfeit products is poor, and the fonts are blurred. 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.
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 hand, 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 classified as mass-produced products, and the quality is mostly guaranteed. In addition, it is necessary to check the appearance of the LED explosion-proof lamp for cracks or looseness, and observe whether there are traces of prying on the interface. If there is, it means that the product is inferior. Genuine LED explosion-proof 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, 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.
Look at the temperature at work:
In the working state, the temperature of the genuine LED lamp 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.
Look at the electromagnetic interference situation:
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 on the outer packaging that passes the test when purchasing LED lights. At the time of purchase, consumers can use the terminal wave radio for testing. Place the radio near the LED explosion-proof lamp after power-on, and observe the noise in the radio. The lower the noise, the better the electromagnetic compatibility of the product.
