Lighting is an important aspect when it comes to interior design. When done correctly, it can provide any room with friendly lighting and a perfect atmosphere. One of the popular lighting fixtures to improve the lighting plan of a room is the downlight. This type is installed in hidden areas or mostly in the ceiling. The downlight effectively help to improve the quality of light in any place where it is installed. They are concave in the ceiling and direct the light down in a narrow beam. They are mostly like a hidden luminaire, which is why the light seems to come directly from the ceiling instead of a traditional luminaire. They are mostly round, but you can still find other shapes.
