Teach you how to identify the advantages and disadvantages of LED lights

When faced with a large number of brands and different prices of LED lights, many consumers do not know how to buy, nor do they know how to distinguish the quality of their quality. In this regard, the industry has summed up the four points to pay attention to the purchase of LED lights to help consumers easily identify.

1. Look at product packaging and trademarks

This is the simplest and most intuitive method of identification. The packaging of genuine LED lamps should be marked with the rated voltage, voltage range, rated power and other information, as well as brand trademarks and related certification marks. The trademark of the genuine LED lamp on the outer package has better printing quality, the font is clear, and it is not easy to fall off. That is, it is wiped with a soft and damp cloth, and the trademark is still legible. The poor quality of the trademark of the shoddy products is poor, the fonts are fuzzy, and the trademarks of some products can be wiped with a damp cloth. In addition, there are no printed trademarks and related certification marks on the packaging of some inferior products.

2. Look at the appearance of the lamp

Authentic LED lights use three-color light tubes, and the color of the light tube is whiter. After being covered by hand, the color of the tube will look whiter. When purchasing, consumers can compare multiple LED lamps for comparison. Products with good lamp shape and size are generally mass-produced products, and the quality is mostly guaranteed. In addition, look at the appearance of the LED lamp for cracks and looseness, and observe whether the interface has been tampered with, and if so, it is a poor quality product. Genuine LED lights do not appear to be loose or boring during installation or disassembly.

Consumers can also identify the quality of the LED lamp shell material, the authentic shell of the LED lamp flame retardant material, the texture is relatively rough, similar to frosted glass. Inferior products are made of ordinary plastics with a smooth and shiny surface. These materials are characterized by easy deformation and flammability.

3. Looking at the temperature at work

In working condition, the temperature of the genuine LED lamp will not be too high and it can be touched by hand. If a product is heated at a significant temperature during the work, it indicates a problem with its quality. In addition, the LED lights flashing, it also shows its quality problems.

4. Look at electromagnetic interference

In China, electromagnetic compatibility is an important indicator for checking the qualification of electrical products. Therefore, when consumers purchase LED lights, they can check whether there are relevant marks on the packaging.

At the time of purchase, consumers can use the short-wave radio for testing. Place the radio near the powered LED light and observe the noise from the radio. The lower the noise, the better the product's electromagnetic compatibility.
