... had friend with
lamps going super bright , he got electrician to
go thru his power panel, and outlets- several 100$
later, got hold of power company, and they kept
stalling him (no problem found).

I'm surprised it took more than a few minutes to diagnose this. A floating
neutral is about the only thing that can cause that symptom in just one
house.
