Is it truly silent and hum-free, or should I be looking at the pricier ones for silent operation?

I thought I was not allowed on Amazon anymore. I don't know who the supplier was but yes they were hum free, light free and didn't work at all and that was four out of four light fixtures. I am sure they did not post my feedback as I cancelled my account with Amazon. Funny as they did not give a hoot when I closed my account and still want me to leave feedback.

Yes, it has a electronic ballast. They do not " hum" like the old magnetic ballasts. I have been a Liscensed Electricial for 23 years and have watched these electronic ballasts slowly replace the magnetic ballast. The only down side I see is that they don,t seem to last as long. Example, I work in a Medical building that was built in 1978. Some of the original lights are still in service. So these fixtures have ballasts that have lasted 35 years Wow !! Once a covert them and install a new " electronic " ballast I end up replacing it agin 5 or 7 years later.

They are pretty good lights. When they are running they are good. When you turn them off, they make slightcracking sounds. Warm covers cooling off is my theory. It doesn't last that long...

The GE Advantage Fluoresent is hum-free and a great value for the price. It is hard wired over my kitchen sink.

There is a hum when it starts then it fades away. I use these in our vacation rental house as a quite alternative heat choice for our visitors. I also use this make in customers houses, our main house and my wife's store. I do not find them noisy.

I have not noticed any hum with this transformer. It is well made and should perform well. All transformers do hum a little bit because of the 60 hertz signal but it shouldn't be excessive. Hum can be reduced by mounting on a soft surface such as rubber washers or pad. Loosen and then re-tighten the lamination screws. Loose plates are usually the cause of hum.

There is a hum but not an annoying hum. My son who is sensitive to sound (like a dog) doesn't seem to mind. I bought this last December, he has it on a timer and it goes on every night, still working a year later.

No. You can unplug it. Also, there is no "hum" like other devices give off when they are on, but there is no sound. So, even though I keep it plugged in, it never hums or pops like other speakers do.

This is the second one I've had. Both were extremely quiet. If I stick my head under the sink I can hear a slight hum. Sounds like it might have a problem.

I purchased one about 5 months ago and installed it and it works great but it does have a low humming when its on. You can here it working but its not very loud.

It's actually very quiet...although in order to make it so I needed to wedge the power source between a small piece of wood and the wall so it didn't vibrate...after that; hardly any noise at all.

It has a slight hum, but not noticeably loud. I've had it for about 6 months, and there's nothing I would complain about it

it's almost silent in 1, and in 2 there's a very low hum. The next one bigger has three speeds, the first two are almost silent.

I use mine to direct insert my guitar and keyboards to my computer. I have not noticed any "hum" in any of my recordings. I haven't use channel 1 (microphone vocal), so I can't help with the phantom powered channel.

If you're 100% sure it's not the source, then yes. I don't have hum unless I am on high volume but I have had a lot of source hum from my sound card. So check that out before shipping it off.

You'd hear it hum in a small bedroom with no background noise and even then, anything other than what I mentioned you have to put your ear next to it to make sure it's functioning. It's quiet

I use it to record through, and can say I have no evidence of a hum. A hum is usually a sign of a ground loop, so I would suggest trying an decoupler (hum buster) if it persists when connecting your devices.

I think that it is very quiet. I only use it to backup my system and it is not on all of the time. I have not noticed any noise.

I have not heard the hum so it must be quiet. I bought mine last Summer and it is great. I brought it outside and let it project into my canopy of trees. Incredible. Being it is LASERS I would say do not drop it or let anyone look directly into it. But it is a great buy I will never regret.

I have not heard any humming over the speakers. I'm pretty happy with my purchase and I have a Bose Cinemate surround system.
