Basic 12-15W is enough. (Don't be too low-end products, the efficiency of general products should be more than 60lm W, 80lm to calculate, 12W has 1000lm illumination, enough).
According to the consumption quota (actual consumption + loss), indoor floor tiles need 64 floor tiles of 400X400 every 10, then 16 floors need 16 10X64 = floor tiles, you can buy 103 on the line.
