Mazda (light bulb)

Mazda was a trademarked name registered by General Electric (GE) in 1909 for incandescent light bulbs.

The company chose the name due to its association with Ahura Mazda, the transcendental and universal God of Zoroastrianism, whose name means light of wisdom in the Avestan language.

GE promoted the mark as identifying tungsten filament bulbs with predictable performance and life expectancy.

GE also licensed the Mazda name, socket sizes, and tungsten filament technology to other manufacturers to establish a standard for lighting.

GE's patents on the tungsten filament lamp expired in the late 1930s, and other forms of lighting were becoming more important than incandescent bulbs.
