Sounds like bad grounding at both the house and utility.
I have to wonder if any electrician ever took the time to put a multi-meter across the mains to check the input volage and phase of the lines, almost sounds like one of the grounds and one of the phases got swapped when derpy mcmoron from the utility installed the “Smart” ie. Dumbass meter.
Usually most electrical panels have 220 comming in it is split down two sides of the electrical panel, with each “leg” being 110v but running at a different phase.
Alternating current phases back and forth from +110 v to -110 volts once ever 1/60th of a seconds.
When one leg is at +110v at the same the other leg is -110v, the commond or “ground” is at 0 or zero volts.
The bus bars is most circuit boxes have alternating legs so that each breaker you add is on a differnt leg, this is why a 220v breaker is twice as thick because it draws from BOTH legs, where as a regular 110v draws from just one leg and the other side is the common.
220V dyers and other 220v outlets are different and have to have 3 contacts as they use 2 legs and the common, unlikle the regular 2 prong outlet which is one leg and a common.
Blowing out the light sounds like the moron connected the common on the house to one of the legs...
How do i know this? well a couple of years ago I got Air Conditionign installed and my brother being a consumate electrician patiently explained it to me and I have a good memory/logical mind.
