Designed in 1962 by Achille Castiglioni, the Arco lamp is a timeless classic—and this riff on it is even better. The solid charcoal-colored marble base and matching lampshade project a picture of elegance, while the adjustable steel arm adds scale and drama. A floor on/off switch makes shutting down for the night that much easier. Note: As with all our lamps, the first light bulb is on us.
