I previously purchased another brand and it created buzz in my home radio. I read that lights should be FCC rated. Do these have the FCC symbol?

Yes, But I don't understand why that would ensure a "no buzz" scenario. Perhaps your home radio needs to be looked at as the culprit!

Yes it does have the FCC symbol on the side of the box it has a capital " F" with a capital "c" and a small "c" almost engulfed by the capital c , so that's gotta be the FCC symbol, hope that helps

2800 Lumens, 45 watts. They fit in a standard medium base fixture. There is a faint buzz, but it's not intrusive. I have six installed in my garage and only hear the buzzing if I'm listening for it. I suppose it would be more noticeable in other environments, but it doesn't bother me at all.

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

No, use at your own risk. I used these to put LED in California CFL fixtures. Very low wattage.

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.

They dim fine. I had issue with 2 out of 14 that buzzed. I notice that they only buzz at particular levels. returned the 2 and end up with 1 still buzzing. I move that one to a different fixture with dimmer and the buzzed keep on. so in the end I just move it to an on/off lamp.

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.

I have a 55" led and had this buzzing that would only happen at night. A flood light was on the same circuit in my house and when it would turn on I would get the buzz. When I turned it off the buzz is completely gone.

Marc, why did you answer a question about frequency range by stating where you bought lights? No one has answered the original question and it is very basic information.

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 have a track lighting system with an old, round dimmer knob. They work fine, but do not go down to the very dim light that old bulbs could go down to. I'd estimate they dim to about 25% of full strength, when old light bulbs I could get to dim down to about 2-5%. I do not hear any buzzing when I dim them.

That depends on the circuitry of the light. They did not perform well with the 10 watt LEDs as the bleed through was enough to cause the LED light to pulse. I had my best luck with the Hubbell motion detectors. Direct wire, no problems. While they are almost twice the price, they function well where all the others failed. I spent more money trying to find one that worked.

I've discarded the packaging but I believe these are not dimmable CFLs...very few are and when they do offer this feature, they tend to make a big deal about the feature and cost a lot more. Sorry I can't help any better.

I used Leviton 6674-P0W SureSlide Universal 150-Watt LED and CFL/600-Watt Incandescent Dimmer $18. also available at home depot. No issues and no buzzing. Easy to install.

Hello, I have a non ELV dimmer. The bulbs buzz very loud so I am returning them. They do however produce a nice warm, bright light. The product seems to be very high quality. I believe the issue is with my light switch and/or fixture. I hoped these were a perfect swap-out for incandescents on a 5-bulb light fixture. The buz was just plain too loud. Not worth the money / long term savings ... especially at the premium price.

I have never heard buzzing from mine . All pancake lights in the motorhome were replaced with these.

Don't know. I wrote the vendor and they said bad luck we won't take them back. I will avoid buying these lights.
