[Source: "High-tech LED-lighting market" June issue / reporter Zhang Wei] With the popularity of e-commerce, many LED companies choose to directly sell products online, and monthly product sales are surprising. According to data released by Taobao.com, the top eight sellers of monthly sales, tens of thousands of LED product sales orders, and the low price, many people in the industry are unbelievable.

The 3W LED bulbs sold in many shops on Taobao are branded with a service life of 30,000 hours, but the price is around 10 yuan. When the reporter investigated the terminal market, the first reaction of many merchants was that the price was low. “Even if the product is assembled, at this price, the assembled parts can only use the worst materials, and the quality is difficult to guarantee, let alone the service life of 30,000 hours.â€
Questioning the online product reporter immediately selected a shop called Fulaiya on Taobao. He took a 3W bulb at a price of 10.88 yuan. The seller told the reporter that the shop belongs to the factory directly, and the factory is located in Cixi, Zhejiang. The reason why the low price is because the product has government subsidies, and the chip is used in Taiwan, the service life is up to 30,000 hours, and the warranty is 5 years. Annual warranty. 
When I got the product, I found that the product was a bit awkward in appearance than what was described on the online store. Immediately, the author took the product to the Shenzhen Huaqiang North LED Purchasing Trading Center to open the product, and asked the accessory manufacturer to confirm whether the accessories inside were true to the description on the online store.
However, the answers given by many LED accessories manufacturers are the same: the light unpacking products can't see which manufacturer belongs to which manufacturers, but also the conclusion that the quality can be excellent. It is necessary to find professional engineers to use the instruments to detect them. .
Huaqiang North Wanjia LED lighting accessories store manager told reporters: "The wafer flux is generally 100-110 lumens, the market wholesale price is 1.5-1.8 yuan / piece, the minimum wholesale price of constant current power supply is about 3W2.8 yuan, Drive on 3 yuan, plus a cheap shell, one year warranty, according to the configuration of Fulaiya, the minimum set is 13.5 yuan."
"And the work is very poor. If you change the lamp beads, the outer casing will be difficult to screw on. The power supply used by Fulaiya is not very good. The market price of this power supply is about 2 yuan, and the warranty is 1 year. Now this market rarely sells this. Power supply, the power supply and the electric seat can not be stuck together in the installation, the heat dissipation effect is poor, and it is easy to break. We all use the spiral method to stick."
Any enterprise will not make a loss-making business. Ms. Huang, the manager of Guangyi Lighting, told the author: "The manufacturer at 10.88 yuan must earn at least a little more, so the cost of the manufacturer will be lower. According to the configuration of Fulaiya, the worst material is used. Taiwan The wafer of flakes is 0.8 yuan/piece, the cheapest power source for constant current power supply is about 2 yuan, and the shell of Zhongshan is 1.5 yuan. The drive is at 3 yuan, and the heat dissipation effect is very poor. The price of such a combination is 8.5 yuan. But such a product is very It is easy to turn off the lights and the quality of the products is unstable."
For the same product, consumers also have different opinions. Some people give praise, but there are also consumers' evaluation: "The product bulb is not too bright, super bright is a little tricky, the service is poor, the packaging is not qualified, there is no mark on the bulb, I don't know how big the bulb is, like three products. ."
The detection of non-standard snow Wright product testing center belongs to the national testing center. The reporter sent the Fulai Ya 3W bulb to the Xuelaite Testing Center for testing. The results showed that the product was not up to standard. According to the national standard GB/T 24908-2010, it can only be judged that the light effect of this lamp belongs to level 2, the color rendering index is required to be greater than 80, the color tolerance is less than 7, and the measured color rendering index is now 65.8. The color tolerance is 5.1. Therefore, the color tolerance is acceptable, but the color rendering index is not up to standard. 
To determine the quality of a lamp depends on the luminous flux, light efficiency, power factor, color rendering index and safety related tests. For example, if the good quality 3W LED bulb light flux is less than 250LM, the light efficiency is greater than 60, the power factor is greater than 0.5, the color rendering index is greater than 60 and these scalars should be much larger than the required light.
The test results show that the current low-end LED products and energy-saving lamps have no advantage, the Fulaiya 3W bulb is equivalent to 7W energy-saving lamps. Experts pointed out that the service life of Fulaiya 3W bulb is estimated to be 6000-8000 hours, which is inconsistent with Fulaiya's promotion of 30,000 hours. If it reaches the national standard 3W bulb, the ex-factory price should be 20-25 yuan.
The reporter bought a large number of 3W bulbs on Taobao.com, and cooperated with the Snow Wright Product Testing Center. After testing, many products were not up to standard. “Taobao has a lot of 3W bulbs with a price of more than 10 yuan. Can the quality be There must be a question mark on the customs clearance," said the person in charge of the testing center.
