I love commercial inspections..Yep!

Did you try your voltage ticker on the wires for the suspect lights?

Yep Carl. And I bet he finds some current in the neutral even when the switch to the lights is off. It’s enough to make the fluorescents glow dimly.

Yes, it is true, they will glow if wired reverse also. Could also be a slowly dying emergency power battery somewhere.
