Here's an interesting one. We noticed this last year as a reissue via an eBay seller, although doubts were raised as to whether it was actually available or a pre-order. Now, a mainstream design retailer has the Harvey Guzzini Sorella lamp up for sale.
That retailer is Panik Design, which has the reissued Nemo Cassina lamp on its site right now and available to order, although delivery is down as '15 – 20 days'. That sounds like a pre-order to me, but not that long to wait. If you want one, give them a call.
The table light itself is a space classic, dating from 1972 and best remembered from appearances in the likes of Space 1999 and James Bond's Moonraker. Anything futuristic from that era, if you like. It is made of polycarbonate, in a 'shiny white' finish, with the light angled down from that wide opening.
£128 is the price of this particular reissue.
