Comparison of T8 tube and energy-saving lamp
The comparative advantages of T8 lamps and energy-saving lamps: Compared with energy-saving lamps of the same brightness, T8 lamps are cheaper than energy-saving lamps. Compared with traditional incandescent bulbs, it has better power conversion efficiency, less heat generation, and higher color rendering. Because it has been widely used, people have generally understood the structure and performance of the product, and the supporting product technology is also very mature, so it is used in a large area. Disadvantages Current energy-saving lamps are more energy-efficient than T8 tubes, especially spiral fluorescent lamps. The current T5 electronic energy-saving lamp tube saves more than 40% of the electricity compared to the T8 traditional lamp. In addition, the T8 tube contains a mixture of halogen powder and liquid mercury, which has no recycling value after damage and seriously pollutes the environment.
Environmental problems caused by T8 lamps: In fact, not only T8 lamps, but all fluorescent tubes contain mercury, which is harmful to humans. Disposing of fluorescent tubes indiscriminately can cause damage to the environment, so disposal of discarded fluorescent tubes becomes a problem. At present, only some countries and regions (for example: South Korea, Brazil, and Taiwan) will recycle waste fluorescent tubes and dispose of them safely. Since only mercury vapor can be used in the fluorescent tube, the actual mercury content is very low (less than 1 mg), and it is difficult to recover by pumping air first. The gradual popularity of solid-state mercury fluorescent tubes can alleviate this difficulty.
