Velux created the flat glass Sun Tunnel skylight for situations where a typical acrylic dome is impractical or violates local law. The 14-inch sun tunnel lets light into hallways, closets, stairways, bathrooms, or laundry rooms, Velux says. The optional ZTB Manual Blackout shade is a fabric-covered disc that clings to magnets behind the skylight's rim and attaches to a rod for easy placement and removal. 800.888.3589. www.veluxusa.com.
