Mazda originally, but by this point, Mazda was part of Thorn and they ultimately dropped the Mazda / Ekco / Atlas / Omega branding on their lamps and fittings and it all just bacame Thorn. Altlas did appear again later on their control gear and the Mazda name returned on a lot of the Thorn stuff sold into retail stores. GE carried on the Mazda name, but it was ultimately finally removed some time before 2010 (I think when Leicester closed and productiuion moved to Hungary) and everything just bacame GE.
