This is the brightest bulb I have found to replace our e11 bulb in our ceiling fan. The original was 80 watts and $15 each from Lowe's. It's a little brighter and saves MUCH more power. We had no issues with flickering or dimming. Our light is used strictly as an on or off switch (not used as a dimmer). We bought warm white/soft white, this type of lighting makes us feel more relaxed and comfortable compared to bright white. Too bad I didn't find this LED light bulb sooner. Highly recommend and would buy again!
