ARRI Four Leaf Barndoor for the 1,000 and 2,000 Watt Studio Fresnel Light Unit.

• Barndoors narrow the beam spread of a light fixture. They help create a 3-dimensional look to a lighting scheme by placing light in a specific area, or by keeping it away. The more leaves a barndoor set has, or the longer the leaves, the more precisely the beam of light can be controlled.
