Alvar Aalto designed Artek's A110 ceiling lamp, playfully called the Hand Grenade, in 1952. The lamp's beauty is based on its shape, which is simple and timeless. The A110 pendant consists of two cylinders, one inside the other, and the light is reflected upwards at the point where the cylinders meet. As an elegant detail, the A110 lamp features a perforated, brass plated steel ring which diffuses the downward light in a beautiful manner. As many other lamps designed by Aalto, also the Hand Grenade can be suspended in a group.
