The basic parameters of electronic energy-saving bulbs directly affect the quality of their products. The basic parameters are mainly divided into two categories: electrical parameters and optical parameters. The following is a detailed analysis of the quality of energy-saving lamps from several basic technical parameters. 1. The size of the power reflects the power consumption and brightness of the lamp: 9~13W for small area lighting below 10 square meters is suitable. These energy-saving lamps are more mature in technology, relatively cheaper, and more cost-effective. The lighting of more than 10 square meters can choose more than 15W energy-saving lamps, the price of high-power energy-saving lamps is relatively expensive. However, it should be noted that some companies often mark low-power lamps as high-power lamps in order to increase the price, which deceives consumers and directly harms the interests of consumers. 2. Power factor: The experiment proves that the lower the power factor, the worse the energy efficiency ratio, the more easily the two ends of the lamp are blackened prematurely, and the service life is shortened accordingly. Good quality energy-saving lamps, power factor can reach 0.9 or more, the high-power energy-saving lamps produced by famous brand manufacturers use power factor correction technology, and its power factor is higher, almost close to pure resistance. 3. The total amount of current harmonics should generally be less than 50%. The smaller the value, the smaller the harmonic current, and the less the high-frequency interference electronic energy-saving lamps generated during use. 4. Luminous flux and lumen maintenance rate: The former reflects the luminous efficiency of the lamp. The larger the value, the better. The latter indicates the speed of lamp aging. Generally, the lumen maintenance rate after 2000 hours should be above 80%. 5. The color index should generally be between 63 and 85. The larger the value, the closer the spectrum emitted by the lamp is to natural light. The better the vision, the more comfortable the human eye looks. There are many other technical parameters that can be used to evaluate the quality of energy-saving lamps, such as crest factor, start-up time, color tolerance, and so on. So, how do ordinary consumers identify the quality of electronic energy-saving light bulbs? Here are a few simple aspects to introduce how to buy good quality electronic energy-saving light bulbs. 25x10-12 Atv Tire,Atv Tyre,All Terrain Tire Qingdao Friend New Energy Development CO.,LTD , http://www.friendtyres.com
