For safety, hallways should be illuminated every 8 to 10 feet. You can do this with flush-mount ceiling fixtures, wall sconces, recessed fixtures or track lighting. Movable track fixtures can provide the general lighting you need for safety, while allowing you to accent any artwork or family photos to steer the eye.
Stairs should be lighted from top to bottom to prevent accidents, with switches at both ends for convenience. If hall and foyer lighting fixtures do not illuminate the entire stairway, you may consider adding a chain-hung or close-to-ceiling fixture above the stairs.
