How many led downlights do i need for a living room? My living room has 10.8 ft (width) x 21 ft (lenght) x 9 ft (height).

Is it enough if I use 8 LED downlight and each comes with 5 inch, 13 watt, 960 lumen?

I use this calculator to calculate, not sure if it is useful. But, i dont understand what mean by Illumination Intensity. Low Illumination Intensity means that area less exposed to sunlight?
