A precise answer depends on many factors including the roof orientation (i.e. South is always best), tunnel length, tunnel length, tunnel bends, time of day, season of the year, etc. However, generally the 14-inch diameter TGF and TMF units are best for lighting up bathrooms, halls, walk-in closets and areas up to 10′ x 10′. The 21-inch diameter TGF unit is perfect for lighting any type of room up to 15′ x 15′.
