Set Brightness Levels

Lumens measure actual light output (not watts, which measure energy). Getting the right lumen levels ensures each room is properly lit for its purpose.

Lumens vs Watts

Old Way: Watts

Measured energy used. 60W, 75W, 100W bulbs. Doesn't work for LED, a 10W LED equals old 60W.

New Way: Lumens

Measures actual light output. 800 lumens = old 60W. 1100 lumens = old 75W. 1600 lumens = old 100W.

Room Brightness Guidelines

  • Living room: 1,500-3,000 lumens total. 10-20 lumens per sq ft.
  • Kitchen: 3,000-4,000 lumens. 30-40 lumens per sq ft for task areas.
  • Bedroom: 1,000-2,000 lumens. 10-20 lumens per sq ft. Layers help.
  • Bathroom: 1,500-2,000 lumens. 40+ lumens per sq ft at vanity.
  • Home office: 2,000-3,000 lumens. 50+ lumens per sq ft on desk.
  • Dining room: 1,500-2,500 lumens. Lower ambient, focused on table.

Common Bulb Outputs

  • 450 lumens: Accent/decorative. Replaces 40W incandescent.
  • 800 lumens: Standard room lighting. Replaces 60W incandescent.
  • 1100 lumens: Bright room lighting. Replaces 75W incandescent.
  • 1600 lumens: Very bright. Replaces 100W incandescent.
  • 2600+ lumens: Specialty/high-output. Workshops, garages.

Pro Tips

  • •Layer your light: Multiple sources at lower lumens beats one bright source.
  • •Dimmers solve everything: Start bright, dial back as needed.
  • •Age matters: Older eyes need more light. 50+ may need 50% more lumens.
  • •Room color affects it: Dark walls absorb light. May need more lumens.
