Years ago I purchased and installed some four tube 4' fixtures from Home
Depot. This was still in the analog TV days and CH4 TV was actually wiped out
when the lights were on. I examined the innards and discovered "commercial"
ballasts. The manufacturer (forget the name) also made a version with
"residential" (filtered) ballasts.
I talked to the store manager and emphasized that when I walked into the store
I could plainly see "Home" on the outside and politely asked why they were
selling items that were *not* for use in a "Home."
He of course was blindsided by this information and offered to give me a
refund. Since these were installed in my newly built garage and wired through
EMT I was not interested in this option and instead requested that he order the
residential ballasts, which I agreed to install. He did and I did and the
problem was solved.
I priced the ballasts separately and as I recall they were in the $90 range. I
paid $40 something for the fixtures.

I had terrible RFI from fluorescent light fixtures I purchased at the local
They all have "commercial" rated ballasts "ACCUPRO AP-RC-432IP-120-1".
These things suck. I have two different style of lamps with these
fixtures, 8-foot, 4-tube strips and 4x2 foot suspended ceiling fixtures.
These fixtures all made a racket from 15M and up. I had to turn off the
lights in the shop and the shack to work any weak signal stuff on 10M and
I significantly ameliorated this by installing Corcom 10VR3 line filters in
power supply wiring to the fixtures. This took ~20dB of the noise away. I
can have the lights on now.
I don't know why the "Home" store is selling industrial/commercial light
fixtures to homeowners.
Looking back over the archives, I see I am not the only one complaining
about these ballasts.
