These are paper filament incandescent electric light bulbs, invented by Thomas Edison in the late 19th century.
Illumination is produced when an electric current heats the interior wire filament to a high enough temperature to make it glow.
Imagine a love affair that enacts this story of light – the intense heat generated to make love will burn as intensely as it illuminates.
Write the story to the moment when illumination burns. Call the story Edison’s Light.
