Why Is the Price of LED Bubbles so Much Different?

Recently, the major websites have revealed the price comparison of the top ten LED lighting brands LED ball bubble lamps. From the comparison, we can see that the LED ball lights of the same parameter, but the price is much different, such as a brand of 7W ball bubbles 48.9 yuan, but Another brand only needs 13.2 yuan, and the price difference is nearly three times. What is the reason why the price of the same parameter product is very different? Today, I will take you to reveal the difference in the price difference between the LED ball bubble lamp. 1. LED lamp beads Different quality LED lamp beads are very different, and different types of LED lamp beads are also very different. Just like 2835 lamp beads, some only need less than 2 cents, but some need more than 7 cents. In order to pursue low cost, manufacturers use very poor LED lamp beads. Such lamp beads often have very serious light decay. It is basically scrapped for a few months. 2. The price difference between PCB of different materials of PCB is also very large. For example, aluminum substrate is about 200-300 yuan per square meter, FR4 is about 150-200 square meters, and the lowest-end cardboard only costs dozens of dollars a square meter. In fact, it is also an aluminum substrate, the same is FR4, and the price is different. Different materials will have different thermal conductivity. The use of cardboard will cause LED heat to be unable to go out, which will affect the LED life. 3. Different types of power supply are also different, and the power fluctuations are the largest, and the influence on the price of the entire product is the largest. For example, only one block is needed to block the voltage voltage supply, and a better switching power supply requires five or six pieces, and even more than ten pieces. Power supply has a greater impact on the quality of LED light bulbs, and it is easy to fail during the use of poor quality power supply, such as dead lamps, bombers, etc. 4 Different materials are huge in structure, and even the same material structure price is much different. For example, plastic structure cannot be comparable to the metal structure at all. The same material structure, the price of public models and private models is much different. The quality of the material also affects the heat dissipation of the product, and it is more related to the user's safety.
