The shed light: that one I can answer. It was invented by my uncle many years ago. True, it was an adaptation of Edison's bulb, but my uncle named it "The Shed Light". When he needed to see what he was doing in the shed, he'd say, "Turn on the SHED light." Never once did he say, "Turn on the kitchen light" or turn on the livingroom light; nooooooooooooo, it was always "Turn on the shed light." FYI
