Translation of "luminizm" into English

a late-impressionist or neo-impressionist style in painting which devotes great attention to light effects. ##P: But it was not until 1904 that the triumph of French Impressionism was confirmed during an exhibition of La Libre Esthétique, in which Belgium was represented by the Vie et Lumière group, founded in 1904, which introduced “Luminism” as a (late) Belgian current in Impressionism.]
