ABSTRACT:
A lens for a wet environment lighting device that has a fixture with an interior that has an opening, and at least one light source located within the fixture interior. Light from the light source proceeds out through the opening. The lens is for location in front of the fixture and the light source located therein and the lens encloses the opening from the wet environment. The lens has a first light-directing area for directing light in a first beam pattern. The lens also has a second light-directing area, distinct from the first light-directing area, for directing light in a second beam pattern, distinct from the first beam pattern. The lens is positioned relative to fixture and light source therein to select from the distinct beam patterns based on the alignment of the light-directing areas relative to the light source resulting from a positioning of the lens.
