Lighting Strategy. Lighting a living room with a pleasing glow is achieved by placing the recessed lights approximately 2 feet away from the wall for an average 8 foot ceiling. As a result, the light illuminates the ceiling and wall area for a calm mood.

Recessed Lighting Placement calculations for 8 bulbs 1  : Distance between bulbs in the length rows =L/N =16/3= 5.3 feet. 2  Distance between first bulb and the wall in the long rows =5.3 foot/2 = 2.66 feet. 3  Bulbs in the middle row are equally spaced apart and from the wall 16/3 =5.3 feet.
