An optic for aisle lighting includes a portion of an optical material defined by a length and a cross-sectional profile. The cross-sectional profile is characterized by a cavity within the optical material, two upwardly-facing surfaces of the optical material on opposite sides of the cavity from one another, and downwardly-facing surfaces of the optical material. The cavity is bounded by an upward facing aperture, and at least three faces of the optical material that meet at interior angles. Light received through the upward facing aperture is separated at the interior angles, and refracted by the faces of the optical material, into separate light beams equal in number to the faces. The two upwardly-facing surfaces internally reflect the separate light beams downwardly. The downwardly-facing surfaces intercept respective portions of the separate light beams, and refract the portions as they exit the optic.

Each mirror, of the plurality of mirrors, may be configured to reflect a portion of the light as a respective light element of the plurality of light elements. A first light element, of the plurality of light elements, may be reflected onto a first location of the surface. A second light element, of the plurality of light elements, may be reflected onto a second location, of the surface, that is different than the first location.

An LED lightbulb is disclosed. The LED lightbulb includes at least two sets of LEDs that emit two different color temperature light and that are located on a metal core printed circuit board.
