I'm thinking Duke may be switching to the AEL ATBS LED cobras, because today I just saw two new ones that were installed very recently.
Usually they install the AEL 115 FCO HPS or AEL ATB0 or ATB2 LED fixtures.
The ATBS fixtures look more like an HID cobra and aren't flat like the ATB0 and ATB2. They also have ths shiny gray paint like a 115.
New trends that the companies hop on board with.
