Install 90 degree bends over the inlets and outlets and paint the inside of the 90 degree bend black with spray paint. That should stop any light leak you have without a louvre You can use pvc pipe or get those metal pieces designed for ducting, either work just fine. If some still gets out you can always add a little more pipe to the end of the 90 degree to make it longer. Hope that helps.
