The lightweight Nanlite Barndoor for Pavotube II 30X attaches to the LED tube. In the open position, the valve set provides a wide 180-degree beam spread of light. The flaps can be adjusted, which allows you to narrow the light beam to about 5 degrees to highlight specific parts of subjects.

For even more control of the light, use the included 45-degree eggcrate grid. Because the grid consists of several small compartments, the light is flagged so that the light beam does not deviate to the extreme corners. This allows you to accurately control the spread of the light so that it falls even more precisely on your subject.
