Downlights are placed in the centers of the four corners.
First, place a downlight in the center of the four corners of the ceiling, and then measure the distance between downlights on the same side and distribute it evenly, so that the layout of downlights can be easily completed.
Install downlights at an average distance.
Secondly, you can also measure the side length of the ceiling first and calculate the average distance. Then the average distance between the two sides is halved to install downlights, and the middle part is also installed according to the average distance. Downlights should be installed on the same side and on the same line, and the spacing can be slightly different (within 3cm), usually the spacing is about1m.
Please ask the carpenter to open the hole in advance.
In order to ensure the smooth installation of the downlight, it is best to ask the carpenter to help you open the hole in advance when hanging the ceiling. But be careful not to drive on the keel!
