Plastic pendant light fitting. Any info

I'm flummoxed. Never seen the like. Hated it to begin with, love it now, three hours later

it's a style that they used to sell in shops like British home stores back in the 70s

Obviously left an impression...
Did one fall on you?

I remember all the dresses, hairstyles, wallpaper etc from that era, it really made a big impression on 5-year-old Dan and still does
