You _can_ hear it buzz, however, which is a deal breaker for me. At full power it's fine but once you kick down to a lower level it buzzes in all fixtures I tried it in - not terribly loud and much quieter than others, but I can hear it when I'm in a quiet room (which I often am) - if the TV were on or pretty much anything else making noise you'd never notice it but for me it didn't cut it. Also, at very low power it starts to "flicker" slightly - which you should probably expect with fluorescent. This only happens on the "full slide" dimmers I have, not in the 3 way - you have to get it pretty low before it's a problem.
So long story short, depending on how far away the light is from your ear and the "noise floor" in the room, these may work. For high ceilings in recessed lights it'd be fine - but for close lights where you might be reading or working, you'll probably hear them humming when not at full power.
I've had them for 2 weeks now and here is the summary: Yes, the dimming functionality also works. However, you need to run the bulbs for about 5 minutes before the dimming works well without obvious flickering. In one of my dimmers (multi-bulb fixture), I get a slight buzz at the light no matter how long the lights have been on. However, you won't notice the noise unless you actually go near the bulbs and pay attention. Note, at max settings there is no flickering or buzzing anytime. So overall these are good enough for what I need and I look forward to the electricity savings!
I will give these 2 stars. After 1 year of usage the bulbs started overheating and burning out. I'm going to wait for LED lights and bypass the CFL phenomenon.
I have had them for 2-3 months now and no regrets. They shine as a sun. They are better than the no dimmable light bulbs that I bought at the store. And yes, they are dimmable and they work.
The only thing could be the delivery, that takes a time. Although the seller will send you an email confirming the purchase and shipping date, I was not able to track the product. However It arrived. Order them but expect them to arrive 1 -2 weeks after (in the worst scenario). I should not be an issue if you are not in a hurry.
You won't be disappointed.
And, of course, you will contribute to save our planet.
I read the reviews and these looked pretty good. The only thing they didn't tell you was that they cannot be used in an enclosed fixture. The only place that limitation is mentioned is in small type on the bulb base.
Of course I didn't see that until the bulbs burned out. They only lasted about a week. I don't know of any dimmable fluorescent bulb that can be used in an enclose fixture. There should have been a better warning on the package and in the specifications. i am very displeased.
I CONTACTED THE MANUFACTURER WHO ASKED ME TO MAIL HIM THE BULBS SO THAT THEY COULD DETERMINE THE REASONS FOR THEIR FAILURE. HE PROMISED TO SEND ME OUT ADDITIONAL BULBS TO COMPENSATE ME FOR ADDITIONAL FAILURES AND FOR THE COST OF SHIPPING. I HAVE NOT HEARD BACK FROM HIM AFTER REPEATED INQUIRIES.

They're nice until they stop working. And they stop working (on average) within 3-7 months. Sometimes, they're bad right out of the box. Read morePublished on September 23, 2009 by TweatyB
