The first thing I'd do is tell him you don't want to alarm
him, but you are a little concerned. When a device is making
noise that sometimes means it is sparking someplace inside.
It could be a bad ballast transformer design, or bad pin
connections to the lamps, but it isn't normal for lights to
make bad electrical noise that can be heard at a long
distance.
See what he thinks.
