The answer really depends on many factors including the roof orientation (i.e. South-facing is always best), the tunnel length, tunnel angles, time of day, season of the year and other factors. Typically, the 14-inch diameter is best for lighting up bathrooms, halls, walk-in closets and areas up to 10′ x 10′. The 22-inch diameter sun tunnel is perfect for lighting any type of room up to 15′ x 15′.
