​central feature of the AYNO lighting family is a fiberglass rod, which is stretched to the bow by the luminaire cable. the inherent tension of the rod allows a lamp without any joints. by sliding the two adjustment rings at top and bottom, the fiberglass rod is bent into the desired position and the light is directed where needed. the cable tightens the rod into an arc, of which the radius can be varied as required using the adjustment rings. the fine adjustment is done with the swiveling lampshade.
