Here I found this at Cobb Pkwy & Dobbs Dr NW, Kennesaw, GA 30144. I originally mentioned this at Streetviews of Streetlights and here is my proof that I have stopped at this intersection to snap this specimen.
Sweet find! From looking at the other pic, they are 175w mercury. Made by GE, not sure of the precise model designation but it is a variant of the Form 400.
