Moderator lamp
http://dbpedia.org/resource/Moderator_lamp
The moderator lamp is a type of 19th century oil lamp. It displaced the more complex Carcel lamp which used a clockwork pump. Its mechanism was simpler and required less maintenance or repair. The moderator lamp was invented in 1837 by Charles-Louis-Félix Franchot (1809-1881). Like the Carcel lamp the oil reservoir was below the burner and it allowed 360 degree illumination. Earlier oil lamps such as the Argand had a reservoir above the burner which made them top heavy and obscured some of the light. The reliability of the mechanism led to them being adopted in lighthouses.
