Therefore, the application of LED lamp tubes using LEDs as illuminants was born, and it has become the most ideal product to replace fluorescent tubes at the present stage. The installation of LED lamp tube is very simple. When installing, the original fluorescent lamp is removed and replaced with LED lamp tube, and the ballast and starter are removed, so that 220V AC mains power can be directly added to both ends of the LED lamp tube. LED lamps save electricity by more than 70%, and their lifespan is more than 10 times that of ordinary lamps (theoretically, it can reach more than 50,000 hours). It is almost maintenance-free, and there is no need to frequently replace lamps, ballasts, and starters. problems, and the light is soft and the color is pure, which is beneficial to people's vision protection and physical health. However, it also has certain disadvantages: 1. The LED lamp tubes currently on the market to replace traditional fluorescent lamps generally have a lamp tube with a lamp holder.
