A type of oil lamp with a tube-shaped wick that produces a brighter, more efficient flame than traditional flat-wick lamps.
Named after Aimé Argand, a Swiss inventor who created this improved lamp design in the late 1700s. The name became genericized to describe this type of lamp, though it's less common now after electric lighting replaced oil lamps.
Aimé Argand revolutionized indoor lighting before electricity even existed—his tube wick was so much brighter that it transformed how people could read and work at night, and his name became synonymous with this technological jump, like how we still say 'aspirin' even though that's a brand name.
