LED Ceiling light arrangement

[Lord Nemesis]

Need help with choosing the right wattage LED ceiling lights for my new flat.

My living room is 31' 4" x 12' 8" and the false ceiling is shaped like in the depiction below.

I have kept provision for 12 lights in total with 5 in each along the length of the arc on either side and one more on each side. I won't be having any other tube lights in the room. What wattage lights would be enough for each point?

This will solely depend on the purpose of the room at each position. In case your living room is an Open Kitchen + Dining + Hall/Living then the needs would be different. Another consideration would be if different intensity of lighting is required at different parts of the room then you will most likely end up with different sizes of the lamps. There are very good online calculators that give a good idea about the lumens/candles/luminosity based on the height of the room and angle of the LED beams.
