Or machinery that makes MV ballasts (westinghouse ballasts). I heard during the Prohibition during the 1930s people made moonshine (homemade alcohol.) I think the same is happening with MV ballasts.
Just hope they're cheap and QC (Quality Control) is tight. The homebrew ballasts causes the government to see that it's expensive to enforce the ban and gives up, but tells the companies to research ways to improve MV lamps and ballasts.
That's just my dream.
