The distance between the lamp
I suggest in TV background above 3 spotlights in the ceiling is provided with 3 lamp sofa background is the three after the living room and dining room for three pieces of frosted glass cover a square and then put on the inside of the other side of the three T4 tube lamp.
How many do you make? What is the width of your living room?. Better do it on your TV Center, about 50 to the sides!
Usually no guests, no need to open the band. So I suggest you make some shapes on the ceiling. No need to install downlight.
You have lights, then only ten square meters of living room, do not have holes, lights are ok. And now most living room headlamps can selectively turn on the lights.
TV wall center, two meters spacing downlight, centered on the line. In addition, the corresponding sofa top also opens two.
