Oluce have issued Kin, designed for them by Francesco Rota. One of the finish options is copper. The one in the image above is the larger size: Ø30cm (model #479). There is a also a smaller one at Ø15cm (model #478):
Other finishes include a black...
...and also a white, here demonstrating that if one is good, two are better...
...and, if you can, why not three? Or, what the heck, four!
The light sources are a very efficient new generation of LED that runs on mains voltage (so no driver has to be accommodated) and is dimmable -- a 4W ( 320 lm) in the 478 and a 12W (940 lm) in the 479. Enough for a sun tan. Actually, though photometric tables are rare for decorative luminaires, Oluce do them for Kin:
The diffuser (more obvious in the smaller 278) is plexiglas.
Custom arrangements are possible, as are and special versions -- e.g. other colours, such as red:
The result is very versatile, elegant, reasonably priced pendant, in two sizes and with a good light source.
