Looking for a room divider, or just a whimsical feature by a headboard or at the entryway? The Abacus ceiling-to-floor LED pendant provides both light and experiential art. True to its namesake, the Abacus can be customized by moving any of the nine blown glass globes up or down its low-voltage cable "rail", by virtue of tiny grippers on each side that when squeezed, free the globe to slide and stop, exactly where you want to position it. Small steel balls anchor each cable. All Hubbardton Forge products are hand-crafted to last one at a time in Vermont.
