Abstract
A lighting device includes a substantially cylindrical tube defining an interior and an exterior, and a longitudinal axis extending between a first end and a second end. The first end of the tube defines a substantially cylindrical opening disposed in a plane at a first angle that is substantially perpendicular to the longitudinal axis, and the second end of the tube defines a substantially elliptical opening disposed in a plane at a second angle that is substantially non-perpendicular to the longitudinal axis. A reflective surface is provided on the interior of the tube, and a substantially cylindrical flashing is provided about the exterior of the tube. A substantially transparent dome is coupled to the tube proximate the first end, and a diffuser is coupled to the tube proximate the second end.
