Is it normal for these to make a small buzzing noise?

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

Mine does make a very slight fan sound. Only noticeable if it is very quiet.

Not exactly in that condition but yes I have. For example when running a game but just in specific parts of the game like in the menu or something. I think the buzzing comes from the fans but not really sure.

I do not get any buzzing noise out of mine, though I run mine on medium most of the time.

Did you ever get an answer? Mine appears to be buzzing all the time too - I agree. Extremely annoying.

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.

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

No, the buzzing sound is always on, unless you are on mute. I had mine for a couple of months now and it seems to have gotten worse

Nope, more likely than not the buzzing is coming from your output source. Try playing audio from a different source and see what happens.

Shouldn't be the board, do you have a noise reducer? If your only getting from the board though then maybe one of the cords are flawed. Or another pedal on the board may be causing the buzz. Since buzz usually indicates a wire not grounded correctly somewhere. Not sottered right.

I've had the same problem! I've noted that the cheap knockoffs are noisy, even one I bought retail has some buzz. I guess w these you get what you pay for.

I don't think so.. I never had too! As for the noise. I get the same think but only on 1 of the 4 that I bought. Possible defective..

No I have not noticed any strange noise in mine. Sounds like yours is defective.

Yes- It's probably normal not a defect. I've had similar appliances in the past and they all make a hum.

mine make a little sound. you can definitely hear something when they are used especially if you are typing fast.

Yes there is a hum (slight). What I hear is constant; no matter what volume I am set at. I actually had to exchange my first set due to amplifier 'popping'. Again, volume setting did not matter. I have decided not to let this hum problem bother me because it is inaudible when something is playing.

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?
