In early 2020, I acquired a fairly uncommon 2-lamp version of a 1930s GE Novalux from a collector in Iowa, but it had no lenses. I originally put WALK-WAIT lenses into it (a slight historic inaccuracy for a signal that old), but I eventually moved them over to my Finned Marbelite. In December 2020, I had the superb fortune of winning a pair of red 1930s GE Holophane lenses in the a raffle run by a collector on the West Coast. I hooked up an old circuit board controller and paired the light up with my 16″ STOP WHEN FLASHING sign. I really dig it.
