Some testings of various self-luminous burners of which the results were
reported by R. Granjon in 1907, gave the following results for the duty
of each burner, when the pressure was regulated for each burner to that
which afforded the maximum illuminating duty. The duty in the original
paper is given in litres per Carcel-hour. The candle has been taken as
equal to 0.102 Carcel for the conversion to candles per cubic foot.
