Thinking logically, is there any other choice? The Logic LED Wall Sconce by Modern Forms is constructed by a rigid aesthetic, allowing it to be placed onto exterior commercial and residential areas like backyards, patios and balconies. The Logic is a testament to minimalist lighting solutions: Aluminum bands melded together to create a cage free from any unsightly seams or joints around a mitered Glass shade. From within the shade, energy-efficient LED modules provide a soft, diffused light to the immediate area. LED lamping is dimmable with ELV dimmer sold separately. Can be mounted vertically or horizontally.
