Since the world’s first medium pressure mercury vapor lamps were first marketed in 1933, I am beginning to wonder whether there were any mercury vapor fixtures aside from the combination incandescent/mercury vapor daylight art deco pendants that used art deco design elements and ONLY used mercury vapor lamps? For example, were there any art deco street light fixtures that used medium pressure mercury vapor lamps that were manufactured in the mid to late 1930s?
