Do these make a buzzing sound when they are on? I've found that some CFLs are louder than others.

No. They doesn't make any sound. They are good. I am using them from around 15 months. All four are still working.

Mine never failed or buzzed. Don't know what people are talking about had one going on over a year of use now.

I can't hear any buzzing from my CFLs. But that might be just my hearing. I see that another answer talked about the lights failing quickly. While I have not had that problem another customer did. The bulbs come with a support phone number and are distributed by Home Depot.

Don't know about buzzing. Mine never lasted long enough to buzz. Don't buy these bulbs. Gone in a few weeks.

I know this is an old question but I just bought and installed this switch. I was worried (because of this question) about the switch buzzing. I have this hooked up to control 4 Cree 65W equivalent BR30 dimmable LED lights and notice no buzzing sound what so ever. Even at the lowest setting with my ear on the switch, I hear no buzzing.

I do operate (4) of these lights in my ceiling fan and have no issues. The room is a lot brighter than the Compact Flourescent bulbs they replaced. I have ordered over (30) bulbs, some do give a little buzz most don't. Im still pleased with the purchases.Randy

They're not noisy for me. Is it the lights themselves, or the power supply you're using?

I don't know why your specific dimmers buzz, however I will check to see if my dimmers have an identifier on them. They were like $10-15 cheap dimmers from Home Depot. I installed about 25-30 LED kits in my house, all with the same dimmers, no issues or humming. -Bob

No buzzing, but with my dimmer switch you need to go to 50 % before they go on. They are wicked bright though (I have 4 on one switch). Also, once they are on, you can go below the 50%. Seems like there is a lot less control than with incandescent bulbs

No buzz, hum or any sound whatsoever on mine. I think it would depend on the dimmer used, not the bulb. Some dimmers are ok for LED's. Some are not. Excellent bulb and light.

When the TV is turned off there is no fan noise coming from the TV. To my ears, it is completely silent. I have never heard the buzzing sound that some people refer to. Hope this helps.

Re: buzzing. I've purchased a few of these and eventually left them off dimmers due to buzzing. For what it's worth, though, some seem to buzz far more than others (meaning I returned a light and replaced it with one that buzzed much less, then later purchased more and found variation again).Edit: Phillips maps some excellent, though more expensive, LED lights which barely buzz at all on a dimmer.

I also get a slight buzzing. My understanding is that this is common with most LED lighting when they are put on dimmers

Mine work with any type of dimmer. No humming. I see that others have written reviews were they complain about buzzing. I haven't used one on a lamp next to a reading chair where I might notice a hum. I have them in ceiling cans with a dimmer switch. Never noticed a hum or any black spots on the bulb. I'm an mechanical engineer. Sorry, but LED bulbs don't hum when the voltage is reduced.

The buzzing is only present when the backlight is less than 10. I believe its the flourescent bulb buzzing similar to when typical flourescent bulbs are used with a dimmer. I haven't found the sound to be any louder than the fan/hard drive in my Tivo so I'm not worried about it.

I purchased these at Costco and tried to use them in a 2-bulb desk lamp that has a built-in 3-way dimmer. At the brightest setting they were fine, but at the lowest, they were clicking at a very high speed. I am reluctant to call it buzzing. But it was loud and concerning. I don't know if there was a bad bulb in the pack causing the issue as I never swapped them out to try the unused 3rd bulb. I did return them but am considering trying again because the amount of heat coming from those 2 incandescent bulbs is unreal.

I asked some in my family to listen as well. We hear no buzzing on either high or low. These are high quality bulbs. We're very pleased with them.

Haven't noticed a hum. We have 3 of them in our kitchen and, even when things are quiet and the lights are dimmed or all the way up, haven't noticed anything unusual. Wondering if you got a defective batch?

New CFLs turn on within a second with no noticeable warm-up period. Rest at times it depends on the ambient temperature. In my case, it achieve its full brightness in almost no time.

I've never heard any buzzing or "electrical noise". There's normal fan noise on the higher settings. It's virtually inaudible on the lower two settings.
