(disclaimer: I daisy chained my lights and simply tacked the wires to the drywall with supplied staples - but that doesn't mean it meets code).
It's not exposed building wiring...it's cords attached to an "device" and they are not hard-wired. On the "device" side of an outlet, cords are a normal thing. The limit to four units for the type you mention is because the sum of the unit's amperage cannot exceed a particular amount for the components and cords that are attached, tested and certified for the unit.
