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.
Use the lighting formula to get the wattage for the space! (L x W) x 1.5. So a 10â hallway that is 4â wide will be 40 square feet times 1.5 = 60 watts. If each recessed light gives off 20 watts, you would need a minimum of 3 spaced recessed lights.
