Hello, do you want to ask the reason why the suction lamp of NVC lighting didn't see the tube? The sucker lamp illuminated by NVC can't see the reason why the lamp tube is not bright. NVC lighting ceiling lamp adopts LED and surface light source. As the LED light source, that is, the light source of light-emitting diodes, will gradually reduce its luminous lumen with the extension of lighting time, and then it will not light up, resulting in the NVC lighting suction cup lamp can not see the tube.
