14. A system for sanitizing an object, the system comprising:
a housing defining a tunnel, the tunnel extending between an entrance opening and an exit opening, the tunnel having a first lateral side, a second lateral side, a top side, and a bottom side;
a conveyor movable in a first direction to move an object placed on the conveyor through the tunnel from the entrance opening to the exit opening;
a plurality of ultraviolet (UV) light source assemblies positioned about the tunnel with at least one of the plurality of UV light source assemblies along each of the first lateral side, the second lateral side, the top side, and the bottom side of the tunnel, each of the plurality of UV light source assemblies providing a corresponding directional projection of UV light into the tunnel;
wherein at least one of the plurality of ultraviolet (UV) light source assemblies provides a directional projection of UV light that is angularly offset toward the exit opening of the tunnel relative to a plane that is normal to the first direction of the conveyor; and
wherein at least one of the plurality of ultraviolet (UV) light source assemblies provides a directional projection of UV light that is angularly offset toward the entrance opening of the tunnel relative to a plane that is normal to the first direction of the conveyor.
