Our dream house is nearly complete - we move in next week.
But the buzz from the fluorescent lights (we used a lot of them)
sounds like the house is a model airplane taking off.
We *have* to fix it.

I isolated all the ballasts from the fixtures so the fixtures aren't
vibrating, but that only reduced the noise by less than a dB, if at all.
The buzz is coming from inside the ballasts.

Is there anything I can do to improve it?
Is there a company with enough pride to make ballasts vacuum-potted
(or whatever) well enough that they don't buzz?
These mass-produced consumer ballasts are for the birds,
and sound like the bees.
