Small older homes often have harsh overhead lighting. Install dimmers on all the wall switches. Place floor lamps or table lamps near seating. Pairs of lamps are nice for pairs of tables. Wall-mounted lamps are great beside beds. Choose lamp shade of sheer fabric for more light or of metal to focus the light up or down. Overhead track lighting and can lights might require professional installation. Be sure you buy a supply of the bulbs you'll need.
