This is a Mole Richardson 2 Leaf Lightshield for Super-Broad Flood Light.
Barndoors narrow the beam spread of a light fixture. They help create a three-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 can be controlled.
