Kino Flo BRD-P4 (BRDP4, BRD P4, BRD/P4, brd-p4) ParaBeam 410 Barndoors (Set of 4)
Barndoors (sold separately) are available. The most effective ones are the doors opposite the lamp ends. On this axis the doors actually have some effect. The side doors have little effect due to the deep set parabolic reflector. They can be effective from blocking a view from camera.
The ParaBeam has distinct advantages over conventional quartz softlights.
