The price of LED spotlights ranges from several yuan to several hundred yuan. The first is safety and environmental protection. People are users of lighting fixtures. If lamps have fatal risk factors, I believe no one will risk their lives to use them. Therefore, it is very important to prevent lamps from electric leakage, high temperature burns and acute angle cutting. The design scheme of lamps to prevent these risk factors has been repeatedly demonstrated by engineers from many departments, selected high-quality materials and produced by loss-proof technology, and finally passed the power aging test and high-voltage breakdown test before leaving the factory. These high-quality raw materials and rigorous technology ensure the safety of users, but also increase the manufacturing cost. Second, regular companies are filing enterprises, which will be punished and bear the responsibility risk of producing fake and inferior products. No one will take advantage of the fate of the enterprise for petty gain. The cottage workshop is different. Use the worst raw materials as much as possible, and employees are untrained and undocumented. The product is not compensated for electric shock (you can't find their nest). LED spotlights in natural cottage workshops can be produced for a few yuan, and LED spotlights in steam plants need hundreds. Although they are all LED spotlights, one lamp will electrocute people and burn the house, and one lamp is a regular product with safety certification. Of course, the two are not at the same level, and finally the after-sales service. Regular manufacturers' products must have after-sales service (because it is necessary for market development), while cottage products do not change when they go out, and the service life of products is not guaranteed, which is also the reason why regular products are more expensive. In Zhongshan Guzhen, Guangdong Province, you can buy 5W LED spotlights, but the measured power is only 3W. Some even have no switching power supply, and directly use capacitors and resistors to step down the LED power supply, which is also the direct reason for the short life of long-life LED spotlights. Therefore, if you are not too poor to eat, don't buy LED spotlights without factory name, address and certification. When selling LED spotlights in Zhongshan Ancient Town, Guangdong Province, you should polish your eyes and look carefully to avoid harming others and yourself.
