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.
A recessed light can or two lets some moist air into the space above and may be acceptable as it gets diluted above, but with 70 you are perforating your envelope (unless there is another floor above this), so they should be installed with vapor barrier blockouts if unconditioned space above, which will put you at the $100+ range per light installation, plus circuit cost.
