This very special sconce is a truly artistic piece , part of our sculptural lighting line. it has a profound symbolic meaning , expressed by its patterns and inner relationships. it is a sculptural interpretation of the fifth seals from Rudolf Steiner's 'Planetary seals" series the series are seven seal drawings. the fifth one is the one that symbolically represent our own era , and also , to my own taste , one of the most beautiful in the series. according to Steiner , a contemplative observance of the seals have a beneficiary effects , and it's beauty and luxury look will certainly have beneficiary effect for the room itself. the lamp is painted by hand upon a acrylic glass blank relief, and has a reflector , that was designed to maximize the amount of light reflected , in a way that will emphasize the relief patterns on the surface of the lamp. the sconce can be connected directly to a wall power grid , to avoid visible cable to the power outlet. or be supplied with a power cable and inline switch, both transparent , so it doesn't stands out. please give us a note of your preferred type.
