No idea aside from the stuff that’s exposed/was put in places like the garage recently, but the house was built in 1950 so I feel like it’s unlikely to make things convenient in that way.
Also the attic is full of insulation while the basement is mostly finished, so I suspect some house disassembly may be required in places 
.
EDIT: Looks like someone answered the question on this bulb for me, it doesn’t work in a non-neutral setup
