How long is the shelf life of small light bulbs?
At present, there is no relevant regulation on the "shelf life" of energy-saving lamps in China. Energy-saving lamps are mainly composed of lamp tubes, electronic ballasts and lamp holders. Because there are many electronic components in the rectifier of energy-saving lamps, they will age even if they are not used, so energy-saving lamps also have a "shelf life".
At present, the service life of energy-saving lamps produced by regular manufacturers in the market is about 6000-8000 hours. But this is only the test time. In daily use, frequent switching will reduce the life of energy-saving lamps. According to the normal use time, an energy-saving lamp is used for 4 hours a day, switched on and off 6 times a day, and its service life is about two years.
How to see the shelf life: Energy-saving lamps in regular enterprises are generally marked with the production date on the lamps in the form of code spraying, which consumers can see intuitively.
