Rave reviews from designers accompanied the introduction of the Abacus 5-Light Floor-to-Ceiling Plug-in LED Lamp. An extraordinary piece of illumination, the Abacus, true to its namesake, allows for exceptional customization. Its five blown glass globes can be moved up and down their low-voltage cable "rails", by virtue of tiny grippers on each side that allow the globes to be positioned at will. With tiny ceiling anchors for stability, this Abacus Floor lamp can be plugged in to any grounded 3-prong outlet.
