Abstract
A directional lighting fixture having a variable beam angle that is easily adjusted. One or more lighting sources are disposed within a fixture housing. A removable cover is disposed over the open end of the housing. The cover comprises a micro lens structure that defines the beam angle of the light that is emitted from the fixture. The removable cover, or in some configurations portions of the cover, can be easily replaced by the end user to achieve a desired beam angle.
