Do these bulbs emit any buzzing, humming, or other vibrating noise when dimmed on a dimmer? Thanks.

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.

Not for me, if you are asking about the Phillips LED light bulb with the yellow "glass." I have six of them, none buzzes or vibrates when dimmed to any level of illumination. However, minimum illumination (maximum dimness) is not as dim as that given by a tungsten or halogen bulb.

No, thanks goodness, I've not experienced it having a buzzing sound. I know the annoying sound you are talking about because I getthat buzz from a different type fluorescent fixture in my laundry room.

No click or tick heard. Did have one weird experience where they would not come on and base was hot. A replacement incandescent worked fine in the lamp at the time. Removed these bulbs and replaced the next day, and they have worked fine since.

The dimmer itself should not have any affect on buzzing. Flickering could be due to the wiring coming loose when placed back into the wall after attaching. If you've checked the connecters and all is good, try the original switch to determine if it is indeed the product. If that is the case, you should defo return it. If the problem occurs with your old switch, that means the fault is not in the product. Hope this helps.

I have these throughout my home as well as tabletop dimmers. I don't hear buzzing from the dimmers themselves but from the dimmed lights, which is normal. The more you dim the more likely you are to hear a buzz from the light, especially if the full wattage is high and you have it dimmed low. This isn't harmful and in fact significantly lengthens the life of incandescent bulbs.

I have been using these bulbs in a fan/light fixture with a dimmer. Tough duty with the vibration and these bulbs doing great. No problem with using them with dimmer switch.

They will flash if you dim them with cheap dimmers! Most PWM dimmers give specifications for their output. You want a PWM dimmer with a very high frequency output. Without an output above 25 kHz, you may hear a humming or buzzing when dimmed to low levels. Good dimmers are not cheap. If you want very dim lights occasionally, consider installing two sets of strips. A set of 3528 warm white LEDs for low lighting, and a brighter set of 5050 LEDs, perhaps in a "cooler" temperature such as 6000 K.

I just bought six, hooked them up to a Lutron Maestro and all of them buzz when dimmed. If I turn them on all the way they do not buzz but then they are super bright.

I love the light, but yes, I do occasionally get a buzzing sound. Not sure if it's the dimmer switch or not however.

My husband says any fixture can have a dimmer switch attached to it. He says the only requirement for using a dimmer is that you need to pick out the right bulbs for it (ones that allow dimmers). Also, some fixtures may "buzz" a bit with dimmers, and the noise depends on the switch and the bulbs that you purchase. We don't have a dimmer switch attached to these two Progress Lighting fixtures we bought, but we hung them with the bulbs down and used LED lights in them - and we are very pleased with them. We've had them for almost a year now. They look great, light up the room well, and with LED bulbs, they use a lot less energy. (We have dimmers on other fixtures and get a quiet buzzing on a couple of those; we hardly notice the sound when we dim them though.) Good luck!

No, they do not flicker (at least at full power - I don't have any on dimmers yet).

There is a low level buzzing sound from this bulb when you dim it, but it's nowhere near as annoying as flourescent tubes

I have had my lamp for one month now, and I have not heard any buzzing noises. Hope this helped, you might want to get a return.

This 7W LED bulb dims down smoothly with traditional TRIAC dimmers. There is a faint buzzing sound, but I have to listen in closely (within 1 ft) to notice it.

Cree customer support said "some humming is normal with our bulbs". She suggested ELV (electronic low voltage) dimmers, which run about SEVENTY bucks. I can verify by personal experience that if there are many bulbs or they are close to your ears, there can be an unacceptable buzzing with the $20-$25 "C-L" dimmers you can get at Home Depot. The Cree list of compatible dimmers is at http://creebulb.com/Content/downloads/product_info/cree_dimmer_compatibility.pdf Check for the ones that say ELV.

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

They are not dimmable. Tried about 10 different dimmers. You may get lucky enough to have them dim about half way but they will make an unacceptable and annoying humming sound. Do not purchase if you need to dim them.
