Reader's question: How much energy saving is the energy-saving lamp? Why do some energy-saving lamps have a short life span and need to be changed frequently, but not energy-saving?
At present, there are two main types of lights that people often use in their homes. One is incandescent lamps and the other is energy-saving lamps. According to the survey, about 30% of households in China have not used energy-saving lamps. However, in foreign countries, almost all households have the habit of using energy-saving lamps. So, what is the reason why Chinese families do not like energy-saving lamps?
â— Is the energy saving lamp really energy saving?
Due to the unbalanced product quality of energy-saving lamps for a long time, the vicious bidding has plagued the city's reputation for severely damaging energy-saving lamps, causing people to misunderstand energy-saving lamps. Now, as long as you buy energy-saving lamps in the formal market, in general, you can achieve energy-saving and energy-saving purposes.
The energy-saving lamps we are talking about are mainly for incandescent lamps. Mr. Xu Dongliang, the general manager of Dongliang International Lighting Design Center, explained to reporters that the same illumination, the illumination of a 60-watt incandescent lamp can be achieved. Replace it with a 12 watt energy saving lamp. And the life of energy-saving lamps is about five times that of incandescent lamps.
â— Energy-saving lamps are not more expensive than incandescent lamps
Energy-saving lamps are more expensive than incandescent lamps in terms of purchase price, which is one of the main reasons why people are not willing to buy energy-saving lamps. An ordinary incandescent lamp costs about three dollars, and a regular energy-saving lamp may require at least five times the price. But if we calculate it, you will find that a good energy-saving lamp is actually more economical than an incandescent lamp. An incandescent lamp costs only 3 yuan at the time of purchase, but because it has a short life span, you spend 15 yuan to buy 3 incandescent lamps, and the time spent on buying an energy-saving lamp for 15 yuan is about the same. If you use incandescent lamps at home for 100 degrees a month, then you can only use 20 kWh when using energy-saving lamps. Save 80 kWh per month and 960 kWh a year. If you charge 0.5 yuan per kilowatt hour, it is 480 yuan a year.
Expert Tip: Energy-saving lamps are more energy-intensive when switching lights, so try to avoid using energy-saving lamps in places where lights are frequently turned on and off. At present, most energy-saving lamps in China are not available for dimming circuits. When using, it should be used according to the conditions specified in the manual.
Reporter's Note: The reporter learned in an interview that incandescent lamps do have advantages in terms of color rendering and color temperature compared with energy-saving lamps. However, for household electricity, energy-saving lamps can fully meet people's needs. . Since the energy-saving effects achieved by different energy-saving lamps are obviously different, when purchasing energy-saving lamps, they should try to go to the formal market for purchase.

Energy-saving lamps are a common saying. The scientific name is “self-ballasted fluorescent lamps for general lightingâ€, also known as “compact fluorescent lampsâ€. Because its lumens per watt (the unit for measuring the efficiency of an electric light source) is much higher than that of an ordinary incandescent lamp, that is, in the case of the same brightness, the self-ballasted fluorescent lamp for general illumination consumes far less energy than incandescent lamps. Therefore, people call it "energy-saving lamps."
Absorbing solar energy into the lighting industry in Wenzhou, when the energy-saving lamps can really get closer to the lives of the people, what can they bring to the lighting companies? Lightning out the show to see if the city needs night, such as the development of energy-saving lamps, and the development of energy-saving lamps is in the ascendant. Xi'an Semiconductor seizes the hot spot to improve the industrial system.

Nervos is an ambitious newcomer on the crypto market and Changelly has long watched it with interest. The project attracted the attention of investors and developers since its purpose is not to launch another cryptocurrency in the ecosystem. Nervos is a simple connecting database between any blockchains.
Nervos was launched in November 2019 by Nervos Network and aims to fix issues that plague both Bitcoin and Ethereum. Among them are scalability and value differences. To fix them, the Nervos team wants to implement effective scalability and raise the cost of their token by hosting other cryptocurrencies on their blockchain. Nervos supports smart contracts and is censorship-resistant. CKB is a native token of the Nervos network. It scales with the value of other assets stored on the network: the more cryptos and tokens are there, the more valuable CKB becomes. This means that this token will continue raising its value the more attention and assets it attracts. Add to that the support of smart contracts, and you have a nice crypto bridge between different blockchains. Which is exactly what makes it so attractive for both crypto enthusiasts and investors.
