The ceiling lamp is generally equipped with a ballast and a circular light tube. There are two types of ballasts: an inductive ballast and an electronic ballast. Compared with the inductive ballast, the electronic ballast can improve the light efficiency of the lamp and the system, can be started instantaneously, and extend the life of the lamp. At the same time, it has small temperature rise, no noise, small size, light weight, and its power consumption is only 1/3 to 1/4 of that of the inductive ballast, so consumers should choose the electronic ballast ceiling lamp. The circular lamp tube of ceiling lamp has halogen powder and tri color powder, and the tri color powder lamp tube has good color rendering property, high luminous intensity and slow light attenuation; Halogen tube has poor color rendering, low luminosity and fast light attenuation. Distinguish the halogen powder lamp tube from the tri color powder lamp tube. The two lamps can be lit at the same time. Place your hands near the two lamps. You can find that the hand color of the halogen powder lamp tube is white and distorted. The hand color of the tri color powder lamp tube is the natural color of the skin.
