How to choose LED bulb brightness by room
Buy LEDs by lumens for brightness and Kelvin for color. Watts only tell you how much electricity the bulb uses.
Read lumens first
A hallway can live with fewer lumens than a kitchen counter where you use a knife. Start around 450 lumens for a low lamp, and move toward 800 to 1,600 lumens for a task lamp or a bright ceiling fixture, then adjust because paint color changes what you see. Dark paint soaks light up. The paint planning guide is the other half of that choice.
Who this is for
People replacing screw-in bulbs. It is not a lighting design for a commercial shop and it does not size hardwired fixtures.
A room-by-room pass
- List the tasks: walking, reading, cooking, or video calls.
- Pick lumens for the task, then Kelvin. About 2700K feels warm in a living room. About 3000K to 4000K is easier for a desk or a kitchen. Higher Kelvin looks bluer and harsher at night.
- Match the base and the dimmer. Not every LED dims on an old dimmer. The package has to say dimmable, and the dimmer list still matters.
- For a desk, continue with home-office lighting.
Limits
Lumen totals do not account for shades. An enclosed fixture that traps heat can shorten LED life even when the lumen number looked right. Check the package for enclosed-fixture ratings.
Questions readers ask
What does a 60-watt replacement mean?
It is a rough comparison to an old incandescent, not a measure of light. The lumen number on the Lighting Facts label is the brightness.
