How to distinguish between good and bad LED lights
The packaging of genuine LED lights should be marked with rated voltage, voltage range, rated power and other information, as well as brand trademarks and related certification marks。The trademark printing quality on the outer packaging of the genuine LED lamp is better, the font is clear, and it is not easy to fall off. Even if the trademark is wiped with a soft wet cloth, it is still legible。The trademark printing quality of fake and inferior products is poor, the font is fuzzy, and the trademark of some products can be erased with a wet cloth。In addition, there are some inferior products on the outer packaging without printing trademarks and related certification marks。
