Possible definitions for lumina

Luminism
Painting style that emphasizes a particular clarity of light. It is characteristic of the works of a group of U.S. painters of the later 19th cent., influenced by the Hudson River school. Typically landscapes or seascapes, with sky occupying nearly half of the composition, Luminist works are distinguished by cool, clear colors and meticulously detailed objects modeled by light. The most prominent Luminist painters were M. J. Heade and FitzHugh Lane.


aluminum
Metallic chemical element, chemical symbol Al, atomic number 13. A lightweight, silvery-white metal, it is so reactive chemically that it always occurs in compounds. It is the most abundant metallic element in the earth's crust, chiefly in bauxite (its principal ore), feldspars, micas, clay minerals, and laterite. It also occurs in gemstones, such as topaz, garnet, and chrysoberyl; emery, corundum, ruby, and sapphire are crystalline aluminum oxide. Aluminum was first isolated in 1825, became commercially available in the late 19th cent., and is now the most widely used metal after iron. Its surface oxidizes at once to a hard, tough film, deterring further corrosion. Uses include building and construction, corrosion-resistant chemical equipment, auto parts, power transmission lines, photoengraving plates, magnets, and tubes for ointments and pastes. Important compounds include alums; alumina (aluminum oxide), useful as corundum and as a carrier for many catalysts; aluminum chloride, a widely used catalyst for organic syntheses; and aluminum hydroxide, used to waterproof fabrics.
