I have a ceiling fan that uses 7 candelabra bulbs and I got tired of staring at the dim light when it was on. When they arrived I thought they might just be a little brighter than what was there, but today I replaced the top four bulbs with these and wow! I see! My husband found the "Daylight" color (6000K) too much so I've just ordered a warm white (3000K) and will see if it holds up :) Update: Despite a claimed 50,000 hour lifespan they have 1 year warranty. It's been 14 months and two out of four have failed.
