General
The Briteq barndoor was specially developed for the LED Mini Color 7TC. The 7TC's Tri-LED ensures a sublime colour blending that is perfect for theatres, for instance. However when lighting a stage, you'd want to direct the beam to prevent unwanted light on the backdrop.
About barn doors
In lighting, a barn door is a rotatable frame with four separately adjustable flaps that allow for an optimal control over the light beam. You can decide where you want the light to shine and how broad (or narrow) you like the beam to be, easily creating narrow slits to light out specific parts of the stage.
