This wall sconce uses an innovative directional, non-glare and LED lighting system. The light guide transmits light from an LED source at its edge, distributing light evenly over the surface of the light guide through a precisely engineered pattern of light exit points that provide uniform illumination and low glare while maintaining the translucency of an optically clear acrylic disc.
