Trivia and History

The electric light bulb originated at the very start of the 1800s, when English chemist and technician Humphry Davy (also known for his mining Davy lamp, whose sheltered-flame design greatly improved mine safety) developed one of the first arc lamps, which use the brightness of an electric arc ionizing the air to generate light. While greatly inefficient by later standards, the sheer brightness of arc lamps kept them in use for roles such as searchlights and movie projectors until after World War II.

The first commercially successful lightbulb, however, was the incandescent or filament lightbulb, whose first iteration was the carbon-filament bulb developed by Thomas Edison and Joseph Swan (under confused and contentious circumstances) in the 1880s. The standard for the next 100 years and still in use today to an extent, filament lightbulbs heat up a thin filament of material (originally carbon as in Anno 1800; modern bulbs use tungsten) to extreme temperatures, producing a bright glow. While limited in lifespan and delicate, the light from incandescent bulbs was far more bright, efficient, and safe to generate than gas or oil, and electric lighting quickly became the standard in the decades that followed.
