The so-called "clean" does not refer to the cleanliness of the surface and interior of the lamp, but the lamp is a cold light source, does not generate too much heat, and will not attract those insects that like light and heat. Especially in summer, there are many bugs in rural areas.
Some bugs are naturally fond of heat. Incandescent lamps and energy-saving lamps will generate heat after a period of use. This heat is exactly what bugs like, and it is easy to attract bugs. This will undoubtedly bring a lot of pollutants to the surface of the lamp, and the excrement of insects will also make the room very dirty. However, the LED light is a cold light source and will not attract bugs, so there will be no bug excrement. Therefore, LED lights are more "clean".
