Choose LED lights to "four look"
Select LED lights to see four. As LED lights become more and more popular, the market's dazzling styles make consumers unable to start, so how to choose high-quality LED lights? The first step is to look at the outer packaging of the LED lights. The state has requirements for the outsourcing of LED lights, and must indicate the rated voltage, voltage range, rated power, and rated frequency. High-quality LED lamp products have good packaging and printing quality, clear writing, wiping with a damp cloth is not easy to be wiped off, and poor quality products are poorly printed, fonts are fuzzy, some products do not even have a manufacturer's logo, and there is no relevant certification mark. The second step is to watch the LED tube. Putting together multiple LED lights of the same product to watch together, the quality manufacturers generally have good consistency, and there will be no unevenness of the pipe surface. There is a slope between the interface of the high-quality LED lamp and the screw port, which is convenient for installation and prevents the installer from getting an electric shock. Some of the poor quality LED lamp interfaces are rounded and there is a safety hazard. Pull it slightly at the screw buckle, if there is looseness at the interface, it means there is a problem with the quality and should not be purchased. The third step is to explore the temperature. Put the LED light on the electric base for a few minutes. Generally, the temperature of the LED light rises slowly. The temperature touched by the hand is low. If the temperature is high, the life of the LED light will be affected. Do not buy it. The fourth step is the interference test. When the LED light is working, the radio can be turned on and placed near the LED light. The lower the noise emitted by the radio, the better the quality of the LED light.
