Reflector + Stability Insert
Reflector and Stability Inserts are not required for standard use. One 3/16-inch white foamcore insert may be placed near the top as an illumination refinement or near the bottom as a low-position support aid.
One insert maximum per tube.
Choose one position only, or choose no insert. A top and bottom insert should not be used together.
Top Reflector Insert: not needed for 13, 16, or 19-inch tubes; optional for 22, 25, or 28-inch tubes; and recommended for 36, 42, or 48-inch tubes, but still not required. Light travels upward from the Tube Light, meets the reflector, and returns downward into the tube.
Bottom Stability Insert: only needed for outdoor events and not generally required. Light continues upward through the tube, and the insert does not make the tube windproof.
