In the face of various brands, as well as in the face of high and low prices, many consumers do not know how to buy and how to distinguish between good and bad. In this regard, the clown will summarize 4 points for everyone to help consumers buy with peace of mind.
1. Look at the packaging trademark
This is a simple and intuitive way to distinguish fried chicken. The outer packaging of the LED lamp should be marked with information such as the rated voltage, voltage range, and rated power, as well as brand trademarks and related certification marks. There are no printed trademarks and related certification marks on the outer packaging of some inferior products.
2. Look at the appearance
The LED lamp uses three-primary color tubes, and the color of the tube is whiter. After covering it by hand, the color will look whiter. When purchasing, you 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.
The quality of the LED explosion-proof lamp can also be distinguished by its shell material. The plastic shell of the LED explosion-proof lamp is made of flame-retardant materials, such as our aluminum alloy. The inferior products are made of ordinary plastics with smooth and shiny surfaces. It is easily deformed and flammable.
3. Look at the temperature at work
Under working conditions, the temperature of the LED explosion-proof 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 light of the LED explosion-proof lamp flashes, it also indicates that there is a problem with its quality.
4. Look at the anti-electromagnetic interference performance
Electromagnetic compatibility is an important indicator for assessing whether electrical products are qualified. Therefore, when purchasing an LED explosion-proof lamp, you can check whether there is a relevant mark that has passed the test on the outer packaging.
At the time of purchase, you can use the short- and medium-wave radio for testing. Place the radio near the LED explosion-proof lamp after power-on, and observe the noise emitted from the radio. The lower the noise, the better the electromagnetic compatibility of the product.
