These branched pendant lights are by American designer Victor Vetterlein.
The lamps, called Sprig, are made up of tubular plastic elements that branch out from a central pole.
They can be joined together to form a chandelier or clustered to make a floor lamp.
Here's a bit of text from the designer:
The Sprig lamp design is inspired by the fresh growth of plants. A single Sprig lamp makes a pendant light, while multiple Sprig lamps combined build a floor lamp or a chandelier.
Sprig is made of recycled plastic, and the lighting source is a standard compact fluorescent lamp (CFL). The CFL is replaced by unscrewing a lamp arm end cap to access the bulb.
For joining two Sprig lamps together, an accessory package provides one threaded sleeve and a clip-on electrical cord, plug, and screw-in outlet.
