I purchased 14 of these lights for my living room. I put the correct dimmer switch that is designed for LED's. I am hearing a buzzing sound from them.

In my original review I pointed out that these flicker when dimmed, could also be associated with buzzing since the load is on and off. Mine are still going strong after considerable use, however, I rarely dim since the flickering is irritating.

It may be the dimmer, I bought 6 for the economy of energy, one has already burned out, they do not buzz though

I use mine in outside fixtures on a timer. So, they aren't actually dimmed, but the non-dimmable one's I used first failed after not much use. The dimmable ones have been working great, but I don't really dim them. I haven't experienced a buzzing sound on either the non-dimmable or dimmable bulbs, sorry.

I believe you do. The same thing happened to me. I called the distributor of the bulbs and they confirmed that the dimmer model I was using was not compatible. I would recommend calling them to see if any dimmer is compatible, since the specs say they are NOT dimmable. Dimming was not critical for me, so I replaced the dimmer with a simple switch and have had no problems.

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.

Yes. I installed it with 3 CFLs each equivalent to 60 watt std bulbs and it does make a bit of a buzzing noise if dimmer is set all the way up. Pushing it down a bit reduces the buzzing sound.

I have 5 on one Lutron Dimmer (600 watt handling) switch and get no humming. Its perfect for my application.

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.

The switch itself does not ever emit a noise that I can hear. The actual bulbs though, (I am using dimmable LED bulbs) will start to flicker slightly and emit a slight buzzing noise when this dimmer is turned below ~35%. I am able to safely dim down to 40% without any flickering or buzzing whatsoever.

If you experience any hum or buzzing sound, make sure the lights are not on a circuit with a dimmer switch. The Hue lights work best with a toggle power switch. Dimming happens in the LED bulb components.

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!

I've had mine for a year in a kitchen fan/light. No noise. But, LED's seem to be sensitive. They flicker with a power drop/surge. This is with all my LED's.

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

It could possibly be your dimmer. Not all dimmers are compatible with LEDs. Quite often you will need an electronic dimmer that is capable of dimming LEDs.

The lights buzz when they are at a medium level of light. I don't think this is uncommon with LEDs. The buzzing is virtually gone when it is on full power, and very faint when using at the lowest setting (we use it for a night light). I am using the lutron DIVA dimmer the package says it works with.

I don't know if a particular dimmer is recommended, but I'm using the Leviton IPL06-10Z to control 8 of these on our dining table fixture. No humming sounds or any other problems after having these for 4+ months.

Funny you should ask about CREE bulbs & this dimmer... I switched to the CREE bulbs and bought this dimmer as it's listed as compatible. HORRIBLE buzzing, I took the bulbs back to the big box retailer immediately. After much trouble shooting, including testing other bulbs... I realized the low load was the problem. 75w equivilant (13.5w) CREE LED bulbs got rid of the buzzing. FYI: my fixture requires 5 bulbs. I need a minimum of 60 watts total to keep the buzzing at bay in that fixture. I had the same issue in a 3 bulb fixture that needs a minimum of 40 watts.

All of these mini florescent bulbs have small ballasts in the base that control the lighting. They can and often do make a buzzing noise. I have 20 of the 45W lamps and only a few buzz slightly after warming up. I usually have music on when I use them, so it's not noticable for me. If the buzzing is really loud to you, then you might have received a defective batch, in which case I would contact the manufacturer.

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.
