The Optos wall sconce uses two separate optical-effect lenses to produce interesting displays of up/down light. The aluminum body allows for 359 degree rotation and holds the lenses with clips. Our Cool Dicro Lens is a molded borosilicate glass, with a technologically advanced dichroic coating outer application, in a parabolic shape designed to carefully refract the light rays in the light source. The result is an edgy blueish-purple display of light that exudes an energetic mood. When lit this gives off a light that is edgy and vibrant. This handcrafted glass uses a process where every glass is consistently produced using a mold, keeping variations to a minimum. These stylish and functional luminaries are offered in a beautiful Brushed Aluminum finish.
