An unusual four-lamp wall sconce/wall light designed by Simon and Schelle for Sische Lighting during the 1970s in Germany.  The four thick frosted glass square blocks with rounded off edges are secured onto the brass frame with screwable chrome rings. The glass blocks sit on a brass frame with each one connected by feature brass tubes. A push button on/off switch is fitted to one of the the corners of the brass frame.

Each glass block requires an E27 screw in light bulbs.  I have used oversized LED silver capped bulbs in the images but you may wish to use smaller versions.  The silver capped bulbs help to stop glare and reflect the light back through the frosted glass blocks.  A real showstopper of a light.  It could also be used as a flush mount if you wish.
