Choose LED Light Bulbs
Pick bulbs by light output, color, and fitting. Read a concrete example, examine the trade-offs, and try a small exercise to see whether the principle applies to your situation.
What to check first
- Start here. Lumens measure light output; watts measure electricity use.
- Add context. Check color temperature in kelvins for warm or cool appearance.
- Keep in mind. Verify fixture compatibility and dimmer support before purchasing.
An everyday situation
Two bulbs may each consume 8 watts but produce different amounts of light. Lumens tell you output; kelvin temperature describes whether the light looks warmer or cooler. A 2700 K bulb typically feels warmer than a 5000 K bulb.
Choose lighting by task and comfort first, then compare energy cost at equivalent brightness.
Exceptions and local rules
The package must also match socket type, fixture dimensions, dimmer compatibility and any enclosed-fixture rating. “Equivalent wattage” is a marketing comparison, not actual consumption.
Make a useful change
Write down the socket, needed brightness in lumens and preferred color temperature before shopping. Check compatibility with your fixture.
