It seems that the late 2010s Autobahn fixtures (ATB0 and ATB2) and the AEL 247L are affected. Some Lithonia fixtures are as well because I've seen purple parking lot lights.

Are their 245L, their other Autobahn models, wall packs, teardrop, or acorn fixtures affected as well? I’ve never seen one of those go purple.

Everything that had SMD modules and was made from 2018 to 2021 had the issue. It included the AEL Autobahns, post-tops, most Lithonia Lighting products (RSX, D-Series, CSX, Aeris™, Omero™), and a select few Holophane products were affected. Nothing with glass COB optics was affected.
