LED lighting imaginary wattage disrupts the market

On February 24th, LED bulbs sold in a lighting market in Jinan. For the same brand and the same size of the LED bulb, one actual wattage is consistent with the identification power, and the other is a double wattage. Recently, some citizens called the reporters to say that the number of wattages of LED bulbs currently on the market is serious. In the interview, many merchants bluntly said that there are hundreds of LED lamp brands, and most of them are small workshops. The virtual wattage is normal. In addition, if you do not classify or not test, it is difficult for consumers, even businesses, to distinguish between imaginary bulbs.
The 4 watt bulb is actually tested. Only 2 watt bulbs are bought and go home. Mr. Liu recently said that he recently spent 8 yuan on a lighting wholesale market to buy a 3 watt Savoy LED bulb. After using it, he found that the brightness is not as good as the 3 watt incandescent bulb, which makes him feel Very surprised. Subsequently, he took the light bulb to a friend who worked in the quality supervision department and found that the actual power of the light bulb was only 2 watts, which is a serious virtual standard power data.
The energy-saving lamps in my living room changed four bulbs every month. Mr. Qin, a citizen of similar experience with Mr. Liu, said that for the sake of saving electricity, he used ordinary energy-saving lamps before, and replaced LED bulbs from the end of last year. Under the introduction of a friend, the cheaper figure he bought an unknown product produced by a certain enterprise in Fujian, but the phenomenon of light flickering and dimming often occurs during the use, and the brightness is also much worse than that of the energy-saving lamp. After many tossing, Mr. Liu had no choice but to re-use ordinary energy-saving lamps.
The salesperson said that the reporters who are not cheap enough are coming to a lighting wholesale market near the Jinan Bus Terminal. Many merchants have shown the advertising signs of various LED lamps. During the visit, it was found that almost every LED lamp brand sold by each store is different, and the price is very different. Take 7-watt bulbs as an example. Some brands sell for less than 10 yuan, and brands sell for tens of dollars. From the outer packaging, there are both Chinese and English products.
In a lighting store, the reporter saw the Saiwo brand LED bulb purchased by Mr. Liu. There is no certificate of conformity and 3C certification mark on the outer packaging of the bulb. According to the merchant, each Saiwo bulb has two prices, the difference is whether the wattage is true. Take a 4 watt bulb as an example. The price of a product with a price of 10 yuan is slightly better, and the wattage can be basically achieved. The product with a price of 5 yuan cannot guarantee the wattage. This is very normal, the cheap is not enough wattage, this is very clear in our hearts, anyway, the product can be used, that is, the brightness is somewhat different. (Editor: Nicole)
Another merchant told reporters that the price difference is mainly because the chip inside the LED bulb is not the same, the chip has good brightness and durability; the chip is not good, the price is relatively cheap, but the actual number is not enough to mark the wattage, the brightness is obvious difference.
Try not to buy LED bulbs under 10 yuan. If you mix them together, we can hardly distinguish them. A salesperson told the reporter privately that since the outer packaging of the LED bulbs is the same, whether the power is sufficient, not only the customer does not know how to distinguish, if they do not distinguish the shelf sales according to the purchase price, even those dealers can not tell which ones are Good quality products and which are defective products. Many brands are made by ordinary small workshops. According to the person, brands such as Lixin, Delixi, Haizhili, and Ouqi are all unreliable products produced by the southern workshops. Basically, one brand is changed every year, and the wattage is a virtual standard.
How do consumers identify whether the wattage of the mark is true when purchasing an LED bulb? Some merchants advise journalists to try not to buy products under 10 yuan, because most of these prices are imaginary light bulbs. The cost of the chip is there, and the cost of the 4 watt wick is about 3 yuan. If the merchant sells 5 yuan, it must not be lost.
Industry statement: the error exceeds plus or minus 10 as the virtual standard virtual wattage has become the industry's unspoken rules. An industry insider who asked not to be named said that as a manufacturer, it is generally clear whether they are producing LED bulbs with a full wattage. In order to earn the difference, the dealers prefer to purchase these defective products, and the consumer map is cheaper, so that such defective products have always been very marketable.
According to the person, according to the relevant regulations, the power error of the LED bulb is within plus or minus ten percent, that is, if the product is marked with 3 watts, the bulb is actually between 2.7 watts and 3.3 watts. If this standard is exceeded, it is a virtual standard fixture. However, because the cost of violations is too low, such defective products are difficult to thoroughly inspect.
