There are many factories producing LED tubes on the market , and the product quality is very different. The price of LED tubes is transparent and the seven countries are so chaotic. The same specifications are marked by each factory. The price difference is tens of yuan, which is the expert, to the guests. Explain that this huge price difference is not easy. Here are some reasons why the price difference of LED lamps is large:
Many customers like to search for the price of LED lighting products on Taobao before purchasing LED lamps , and then compare the price of our LED lamps manufacturers, take the example of 1.2 meters 18W LED T8 lamps: Taobao price is sold to 30 yuan Some people sell the price to about 100 yuan. Why is the price so different ?
The reason for the different prices is nothing more than the difference in the materials used for LED lamps. Let us explain the three main materials that make up the LED tube - LED light source, power supply, and profile.
1. There are some unsatisfactory businesses who use LEDs with insufficient power when doing LED luminaires, such as using 0.3W or 0.5W lamp beads to replace 1W of power, because the power of the product is low, the lamp and power supply The price will drop drastically. The lamp beads here are the cheapest, and the service life and stability of the products will be different. If so, I will not comment here ! ( For the lamp beads, it is now like Taiwan's package. Generally, it is about one yuan, and the American Puri wants about 2 yuan for a lamp bead. )
2 , the shell is the most light and thin out of the kit, the cost of aluminum is much cheaper, and the cost is reduced. LED lamp heat dissipation is very important. You can check how the LED lamp solves the heat dissipation problem. If the low-cost outer box is used, the outer box may not be able to withstand the heat, and there may be a potential fire hazard ;
3 , if the power supply uses RC and buck, without constant current power, the cost is reduced by half. But the security is not high. The cost has also dropped.
