1. A beam angle-adjustable lighting assembly comprising:
a lighting tower, wherein the lighting tower comprises:
a plurality of layers of lighting elements, wherein each layer of lighting elements is configured to provide a different beam angle of emitted light with respect to light emitted from another layer of lighting elements when reflected from a parabolic reflector, wherein each layer of lighting elements of the plurality of layers of lighting elements is disposed on a plurality of sides of the lighting tower, and wherein the lighting tower is configured to generate a plurality of patterns of light comprising:
a first pattern of light generated via activation of all lighting elements of at least one layer of lighting elements of the plurality of layers of lighting elements; and
a second pattern of light generated via deactivation of all lighting elements disposed along at least one side of the plurality of sides of the lighting tower.
