LED ceiling light is a kind of ceiling light that chooses LED as the light source. It is installed inside the room. Because the upper part of the light fixture is relatively flat and installed close to the roof, it seems to be adsorbed on the roof, so it is called LED ceiling light.
There is a ceiling light from Toppo lighting, size D470mm, The light have below features.
• Features
