Rich,
Thanks for that info. I now know it's technically possible to have a silent or near silent 2x250w Aquaspacelight. I'm not sure why one would buzz and another won't, and I have a feeling it'll be a mystery to AquaMedic as well. I was told I would have my fixture back in about 6 weeks...
Do you have a 2x25w or 3x250w Aquaspacelight?
Yes, I agree it should be silent except for a slight hum if the room is silent and you're standing right next to it.
I've spoken with AquaMedic 3 or 4 times and they agreed it shouldn't be buzzing. They have the light now and gave me a loaner...

I just wish my Aquaspacelight was quiet. Mine hums/buzzes loudly.
