Some embodiments provide an illumination system with an outer housing including a base, a central housing pivotably coupled to the base including a fluid inlet, and an upper housing including a fluid outlet. The inner housing defines a chamber and is coupled to the base, and includes a fluid aperture adjacent to the base, and a fluid aperture adjacent to the upper housing and a viewing aperture. The chamber houses an evaporator system not visible through the outer housing, and an illumination device. Some embodiments include a repellent system with a base including a fluid inlet pivotably coupled to a main housing enclosing an inner region, and including an upper portion with at least one fluid outlet. In some embodiments, an evaporator system within the inner region is not visible through the main housing. Some embodiments include an evaporator assembly that includes a lockable evaporator support to render the system non-refillable.
