Definitions for "Mazda"
Mazda was a trademarked name used by General Electric and others for incandescent light bulbs from 1909 through 1945. The company chose the name due to its association with [Ahura] Mazda, the transcendental and universal God of Zoroastrianism whose name means "[Lord] Wisdom" in the Avestan language.
Just a different pronunciation from the U.S. (Mahz-duh).
