Abstract: A landscape lighting fixture utilizes a cylindrical bollard shroud member which houses an electrical light source, e.g. an LED module. The shroud number extends upwardly from an elongated riser element. A vertically adjustable path hat support system affixed to a path hat circumscribes the shroud member, thereby allowing the path hat to be vertically adjustable in relation to the shroud member. The path hat and path hat support system can also be vertically adjustable along the riser element, without an attached shroud member. In either case, the adjustability of the path hat allows the lighting fixture to provide a wider or narrower light beam angle from the light source without adjusting the illumination from the light source.
