Use more than one height
Ceiling light alone tends to flatten a room. Combine a pendant with table or floor lamps so light reaches the walls and the places where people actually sit.
Keep the color temperature consistent
Warm white bulbs create a softer evening atmosphere. Matching color temperature across nearby fixtures prevents one corner from feeling unexpectedly cool.
Put dimming where routines change
Dining rooms, bedrooms and living rooms do different jobs throughout the day. Dimmers allow the same fixture to support cleaning, working and winding down.
