A 5w or 7w spotlight must be enough. It is recommended to choose a good brand. Philips or tcl NVC lighting is recommended. The spotlight is broken, so it's really troublesome to repair it.
According to the cad drawing you gave me, if all the lights are wrapped up, the living room is 22 meters, the master bedroom 14 meters, the second bedroom 12 meters, the study 12 meters, and the dining room is 30 meters, which is ***90 meters in total.
