I bought these bulbs to use in a floor lamp that has a reading light and a ceiling light. They are rated at 500/1050/1600 lumens but the lumen ratings may not be accurate. They're no brighter at max setting than Feit Electric's own 60W bulb (0M60DM/927CA), which is rated at just 800 lumens, and at medium setting (1050) noticeably dimmer and more yellow than the same 800 lumen lightbulb. They also have an insane power-up delay every time they turn on, even if you turn them off and back on immediately. This is very noticeable with my light as they actually light up BEFORE the 60 watt bulbs when they are first turned on and every time thereafter. Very disappointed with these bulbs; I will return them to Revane as soon as possible.
