I just installed some new Lithonia 8' high output fluorescent fixtures in my
shop and noticed after a couple day's use that one of them has quite a noisy
hum coming from it's ballast. Would I be correct in assuming that a new
light shouldn't have a noisy ballast? Any input is appreciated.
Thanks,
Jerry

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.

Since its only one of the group return it or call the mnfg. perhaps a
ground is missing, loose connection

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.

If only one buy another, switch ballasts and return it.

Yes, this ballast does say "electronic" on it. Thanks everyone for the
replies.

Verify that they are grounded properly. This can be an issue with some
electronic ballasts.

HO and VHO have never been noted for being quiet. That is why they are
usually mounted in areas that it is not an issue.

Do they quiet down after they get warm?
