: Operating voltage is 220V, is a parallel 400V high-voltage capacitor in the circuit above, with the poor quality of the high-voltage parameters perhaps not an explosion caused by heat, or high-voltage capacitor is the negative anti-welding, factories may not have long aging On the factory, the test of time may be bright, but the installation will be up to use a fever, and then an explosion, as well as floor tiles led light is waterproof design, which is sealed, high-voltage capacitors after the explosion pressure can not be released, They led floor tiles burst open at the Lights.

Do not buy the product cheaper plans, the Chinese people in order to reduce costs, dare to do anything, no one would like to buy cheaper products, recommends that you buy products in large quantities, they can buy a cheap and compare your sample, the difference in the That, weigh the consequences before making a decision .220 V directly and through rectification Capacitive step-down circuit is the most unsafe, many manufacturers are now rarely used, are so low, and would like to work directly with 220V, the lamp can Inside a built-in constant current or constant voltage power supply, this circuit if you have a bad LED, LED lamps as a whole is not bright, LED current is also the most unstable, LED lamp life is not the president, it's Current work is subject to the city's electricity because the city's normal fluctuations in electrical voltage is obnoxious, the design may be a time when the 220V current time is right, if the current electricity voltage is 230V or 240V or more, LED The current work on high, LED on the life of decay quickly.

Now available in the market as the internal control barrier LED lights that are controlled circuit, costs were relatively cheap, only a 70-80 yuan (good circuit design, good quality to 140-160 million), but life is very short, failure A high rate, and some works are tens of thousands of light-meter barrier because the quality of manufacturers, and Zhuang Shangqu removed, Jan. 2 million on this project ah installed and removed, such as manufacturers seek compensation for your return, regardless of the manufacturer You, since he could do such a poor-quality products, he will have to cope with his methods, you would not be the first to return.
