The Argand lamp is a type of oil lamp invented in 1780 by Aimé Argand. Its output is 6 to 10 candelas , brighter than that of earlier lamps. Its more complete combustion of the candle wick and oil than in other lamps required much less frequent trimming of the wick.

Starting in 1780, the Argand lamp quickly replaced other oil lamps still in their basic ancient form. These in turn were replaced by the kerosene lamp in about 1850.

The lamp used a similar design to an Argand lamp, adding a parabolic reflector behind the lamp and a magnifying lens made from 4-inch-diameter (100 mm) green bottle glass in front of the lamp. A similar variant using a parabolic reflector was created by the inventor of the Argand lamp, Aimé Argand.
