Design a code-compliant lighting plan with precise fixture spacing.
Quick Answer
For a 20x15 living room, you want relaxed ambient lighting (20 FC). Use about 6 standard 800-lumen recessed cans in a 2x3 grid for even coverage without glare.
Proper lighting design depends on the total area, target light levels (illuminance), and individual fixture output.
Dimensions: Length and Width of the room in feet.
Illuminance (fc): Lighting density measured in footcandles.
Fixture Lumens: Light output of a single bulb or fixture.
