The wattage of cheap LED lamps is imaginary wattage due to the use of inferior chips

The LED bulbs currently on the market have a serious virtual standard wattage phenomenon. Many businesses bluntly say that there are hundreds of LED lamp brands, and most of them are produced by small workshops, and the virtual standard wattage is normal. In addition, if it is not placed in categories or tested, not only consumers but also businesses will find it difficult to distinguish light bulbs with false wattages.

The bulb marked with watts, the actual test is only watts

'Buying a light bulb at home always feels that the brightness is not enough.' A customer bought a watt-watt Sawo LED bulb at a lighting wholesale market, and found that its brightness is not as good as a watt-power incandescent bulb after using it. Then I took the bulb to a friend who worked in the quality supervision department to test and found that the actual power of the bulb was only watts, which belonged to serious virtual standard power data.

The salesperson said that 'the cheapest things are not enough wattage'

I saw that many merchants have put up all kinds of 'LED lamps' advertising signs. Almost every store sells different brands of LED bulbs, and prices vary greatly. Take watt bulbs as an example. Some brands sell for less than RMB, while others sell for dozens of RMB. From the perspective of packaging, there are both Chinese brands and English products.

There is no certificate of conformity and C certification mark on the outer packaging of the Saiwo brand LED bulb. According to the merchant, each Sawo brand bulb has two prices, the difference lies in whether the indicated wattage is true or not. Take a watt light bulb as an example. The quality of a product with a price of RMB is slightly better and can basically reach the specified wattage, while a product with a price of RMB cannot guarantee the wattage.

'This is normal. The cheap ones are not enough wattage. We know this very well in our hearts. Anyway, the product can be used, but the brightness is somewhat different.'

The price difference is mainly because the chips in the LED bulbs are different. The good chips are bright and durable; the bad chips are relatively cheap, but the actual wattage is not enough, and the brightness is obviously different.

Try not to buy LED bulbs below RMB 'If they are sold together, it is difficult to tell the truth. Because the outer packaging of LED bulbs are the same, not only the customer does not know how to distinguish whether the power is sufficient, but if they do not follow the purchase order If the price is divided into shelf sales, even their distributors don’t know which products are of good quality and which are inferior products. Many brands are made by ordinary small workshops.” According to the person, such as Lixin, Delixi, Brands such as Haizhili and Ouqi are all 'unreliable' products produced by southern workshop enterprises. Basically, they change brands every year, and the wattages are all false standards. When consumers buy LED bulbs, how can they tell whether the wattage indicated is true or not? Try not to buy products below RMB yuan, because most of these price points are bulbs with phantom wattage. 'The cost of the chip is there, and the cost of the wick for the tile is about yuan. If the merchant sells the yuan, they must not lose money. Page: The error is more than plus or minus% to be a false standard?

According to the industry: the error exceeds plus or minus% is a false standard 'Virtual standard wattage has become the unspoken rule of the industry.' An industry insider who did not want to be named said that as a manufacturer, it is generally clear whether they produce Full-wattage LED bulb. In order to earn the price difference, dealers prefer to purchase these defective products. In addition, consumers tend to be cheaper, so that such defective products have always been in the market. 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 watts, the actual bulb can be between watts and watts. If it exceeds this standard, it is a virtual standard lamp. However, due to the low cost of violations, it is difficult to thoroughly investigate such defective products.
