How recessed lighting installation works in a Louisville basement
We set the grid off the room rather than off the joists where we can, so the cans line up with the walls and with each other instead of following whatever the framing happens to do. Where a joist lands badly, the housing shifts or the trim size changes rather than leaving an obviously crooked line.
Wall washing matters more than people expect. Cans too close to a wall scallop it, and too far away leaves the perimeter dark, which makes a room feel smaller than it is. Lighting the walls is most of what makes a windowless space feel open.
