The Catellani & Smith U. F Up floor lamp emits its light indirectly upwards towards the ceiling. The lamp is approx. 186 cm high and is available in black or white. The semicircular, U-shaped lamp shade of both versions is inside coated with a gold-coloured foil that reflects the light emitted. Included in delivery is a small, magnetic steel figure that can be attached to or in the lamp shade as desired. On the supply line of the U. F Up a dimmer is integrated. The lamp is switched on or off by briefly pressing the dimmer. By pressing and holding it longer, the light can be dimmed. A memory function saves the last light intensity setting and automatically sets it again when the lamp is next switched on.
