Light Control Device for PavoTube II 6C LED Tube Light The Nanlite PavoTube II 6C Fabric Grid surrounds 10-inch tubes like the PavoTube II 6C and 6XR and minimizes light spill and adds directionality by tightening the beam angle to 40 degrees. Great for selectively lighting subjects without losing the soft quality of light emitted by PavoTubes. Attaches quickly and swiftly via elastic straps and folds down flat for storage and transport.
