From Danish company Halo Design, here is a socket.
As always from this particular brand, you can expect a very high quality. Halo Design has more than 25 years of experience in lamp design, which is evident when you hold one of their products in your hands - and this also applies to their lamp holders.
Use the socket with a lampshade you like - or leave it hanging bare with a smart decoupage bulb in it.
OBS: This is only a socket set, and therefore does not come with a light bulb or lampshade. You must purchase these yourself.
