In 1894 he proposed the lumen and other new measurement units for use in photometry, based on the metre and the Violle candle.
Violle is believed by some to be the secret identity of Fulcanelli, a contemporary French alchemist whose true identity is still debated.

In 1875, Jules Violle resumed the work of Pouillet and offered a somewhat larger estimate of 1.7 kW/m² based, in part, on a celebrated measurement that he made from Mont Blanc in France.
