Those ceiling lamps designed by Alvar Aalto are one of his rarest designs. Called « hand grenade » due to their recognizable shape, they were produced by the end of the 1950’s. The golden color of the brass of those lamps produces a pleasant and diffuse light, creating a very warm atmosphere. Equally obsessed with the quality of the light produced and the aesthetics of the lamp, Alvar Aalto created his lighting fixtures as genuine sculptures. While embracing the trend of functionalism, Aalto developed his own approach, choosing curved lines and organic shapes to convey a more lyrical feel to a primarily functional object.
