It is woven with 75 strands, and weighs 3.6 grams (55.5 grains) per decimeter (3.9 inches) of length. Carcel designed a lamp with the oil reservoir under the burner, in the body of the lamp. The numerous experiments of Crova showed that two very different carcel lamps, compared within an hour, give indications whose variations amount to from 2 per cent to 3 per cent at most. The pump was immersed in the lamp oil reservoir. . An obsolete unit of luminous intensity, 19th century, primarily used in France, approximately 9.61 international candles, approximately 0.98 candela. The vegetable - mostly colza - oils then available were thick and would not travel far up a wick. . . What does carcel lamp mean?

Another innovative feature was that fuel was pumped into the wick tubes at a greater volume than was necessary for burning so that it overflowed the top of the wicks, thus cooling the burner.. The lamp should consume 42 grams of oil per hour; when the consumption falls below 38 grams or rises above 46 grams, the test results should be discarded. The clockwork movement (in the foot) controls a pump located in the oil tank to raise the oil directly to the nozzle. . The first generation of lamps (1800-1810) had to be lifted to wind the movement for the underside of the lamp (Mulum model). In this modification the oil reservoir is placed in the base of the lamp and the oil is raised to the level of the top of the wick by means of clock-work which operates two small pumps in the instrument.
