Then the lighting is installed.

Mount two -tier ceilings made of drywall are performed in two stages. First the first tier, then the structure is installed under the second. Then the lighting is installed. You can place the main source of lighting in the center, and add small auxiliary at the edges. Or evenly distribute the same light sources throughout the area. Often, with a two -level ceiling structure, light sources are installed on the side parts of the second tier.
