Hi guys, I have a 24 feet X 15 feet living hall, total size is 360 sq ft.
I wanted to build a L Box surrounding the living hall which will form a shape of rectangle, the wiring man suggested to install total 16 downlights at the L Box area. My questions are:
1) Is 16 downlights too many for a 360sq ft living hall?
2) If the number of downlights is 16, should I use 4" or 6" downlights?
3) What wattage should I use for the bulb if there's 16 downlights? go for lower watt?

Please look at these pictures to get an rough idea of my wiring layout.
