The Catellani & Smith DiscO is a ceiling lamp with an oval reflector. A lamp head is integrated under the reflector. This lamp head illuminates the reflector, so that the light is reflected glare-free into the room. The reflector has a length of 75 cm and a width of 50 cm. It is available in white, gold, copper and silver. The version in white is smooth, the irregular structure of the other versions leads to different light effects. The lamp head is always made of glossy nickel-plated metal. The height of the lamp is 25 cm. The DiscO by Catellani & Smith is operated with an integrated LED, which can be dimmed on site.
