I may be wrong, but my recollection is that all of the units with T-8, high
output tubes HAVE an electronic ballast. Irondog's just got a bad one.

I just installed some new Lithonia 8' high output fluorescent

correct in assuming that a new light shouldn't have a noisy ballast?
Any input is appreciated.
Thanks,

My experience is that these lights do have noisy ballast. Not as bad
as
some, but still they are not what I would call quiet. However I'm keeping
mine. I like the light. If I need a replacement I will try to find
something with electronic ballast.
