This is a half double wire scrim for the Mole Midget Fresnel, or any other fixture that accepts a 5-1/8" accessory.
Full scrims dim the light across the entire beam spread, 1/2 and graduated scrims are used to even the beam spread when lighting a subject or background from an angle.
Keep several densities of scrims available, to be prepared for any lighting situation.
Note: This item requires a barndoor-diffuser holder for use on the Midget Mole (cat. # 24922).
