Figures such as lumens, wattage equivalent, color temperature, and CRI are as published by the seller and are not our measurements. Our method is on the How We Review page.
Frequently Asked Questions
How bright is it?

Is it dimmable?
Yes, the listing says it is dimmable. Check your dimmer.
Where does it rank in your guide?
It is #1 of 8 in our LED filament candelabra bulbs guide, based on listed specifications and not on a score.
Note: switch the power off and let a bulb cool before you change it. Stay within the fixture’s maximum wattage, using the bulb’s actual LED wattage and not the “equivalent” figure. Check whether a bulb is dimmable, and whether it is rated for enclosed or damp locations, before you use it there. Look for a UL or ETL mark, and follow the maker’s instructions. Listings differ; we describe what each maker lists.
