The crystal crushed fiber-optic LED lamp contains white LEDs that illuminate clear crystal rocks in the base and fiber-optic fibers with crushed tips on top and can be used as a table centerpiece or a party decoration. The crushed tips produce a fuller, more even glow than traditional fiber-optic lamp fibers, which display tiny points of light. The lower portion of the base is black, which in low light helps make the lamp appear to be floating in midair. The lamp can run for up to 20 hours on three AAA batteries (sold separately). The base of the lamp measures 3-1/4' high and 3' in diameter. The fibers measure 9-3/4' high.
