Mazda was a trademarked name registered by General Electric (GE) in 1909 for incandescent light bulbs. The name was used from 1909 through 1945 in the United States by GE and Westinghouse. Mazda brand light bulbs were made for decades after 1945 outside the US.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. In 1909 the Mazda name was created for the tungsten filament light bulb. 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.
Tungsten-filament bulbs of the Mazda type were initially more costly than carbon filament bulbs, but used less electricity. Often electrical utilities would trade new lamps for consumers' burned-out bulbs. In at least one case the authority regulating energy rates required the utility to use only tungsten bulbs so as not to inflate customer's energy use. The company dropped the campaign in 1945. 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.77,779 expired in 2000.
