Bollicosa Nautilus has the same blown glass sphere as the Bollicosa indoor with the distinctive bubbly surface caused by the artisan blowing process; the natural irregularities make the material rough and matt and imbue it with a 3D quality that gives it the appearance of a fossilised stone to the naked eye. The outdoor version envelopes the diffuser with a neutral-coloured polypropylene cord net, with knots in contrasting colours, which recalls the hand weaves of the furniture in the Cassina outdoor collection.Outdoor (IP54)Light sources- E27 LED light bulb - not included (EU-UK-China)- E26 LED light bulb - not included (USA-Jap)Light control: RemoteVoltage: 220-240 V (Eu-UK-China) / 100-120 V (USA-Jap)Power: Max 10 W ledBattery: YesPower supply: NoCord length: 2.5 m
