In the face of many brands, LED lights with different prices, many consumers don't know how to choose and buy, also don't know how to distinguish the quality of the wheat from the chaff. To this, the personage inside course of study concluded that the choose and buy LED lights need to focus on four points, to help consumers identify easily.
1. The product packaging and trademark
This is the most simple and intuitive to distinguish method. Authentic LED lights on the outer packing should be marked with the rated voltage, voltage range, rated power, such as information, as well as the brand trademark and related certification marks. Authentic LED lights on the packaging of trademark printing quality is good, the font is clear, not easy to fall off, with a soft wet cloth to wipe, trademark is still clear. False and inferior product logo printing quality is poorer, font fuzzy, the partial products of trademark can be erased with a wet cloth. In addition, there are some bad products on the outer packing of no printing trademark and related certification marks.
2. See the tube appearance
Authentic LED lights use trichromatic lamp, and the color of the lamp is white, cover with the hand, the color will look whiter. When the choose and buy, consumer can put more than LED lights together to compare, tube shape, size consistency better general for large-scale production of products, quality are guaranteed. In addition, it remains to be seen whether the appearance of the LED lights have crack, loose, and observe whether interface has been broken open a trace, if have, explain its is inferior product. Authentic LED lights will not appear in the process of installation, remove loose, a little wait for a phenomenon.
Consumers can also through the LED lamp shell material to identify strengths and weaknesses of its quality, quality goods LED lamp plastic shell with flame retardant materials, the texture is relatively rough, like frosted glass.Inferior products using common plastic, surface smooth and glossy, this kind of material has the characteristics of easy deformation and flammable.
3. The electromagnetic interference
In our country, the electromagnetic compatibility is one of the important indicators assessment electrical appliances product is qualified, because this consumer is when the choose and buy LED lights to see if there are any more through the test on its packaging related logo.
When buying, consumers can use the test medium short wave radio.Puts the radio after electrify near the LED lights, observation of the noise on the radio, the lower the noise indicate the electromagnetic compatibility of the product, the better.
