This is an ARRI Full Double Scrim that fits the 650W Fresnel, Arrisun 2, HMI 200W or any fixture that accepts a 6 5/8" accessory. Scrims are metal screens mounted in a metal frame. They are placed in front of a light to reduce light intensity. ARRI makes four different types of scrims:

• Full Single: This scrim covers the entire lightface and reduces the intensity of the entire light beam.

• Full Double: This scrim covers the whole face of the light. It has two metal screens in it, reducing light intensity by two times the amount of the full single.

• Half Single: This scrim only covers half of the lightface reducing half of the light intensity.

• Half Double: This scrim is the same as the half single but reduces light intensity twice as much.

Half scrims may be rotated in position for more precise control.

Q: 9. I want to use this with a 220v bulb. What do I need as far as power conversion to make this work from an American 120V Edison power supply? Will a standard power converter work or do I need something different?

A: The ARRI 650 Watt Plus Tungsten Fresnel (120-240VAC) is a dual-voltage light fixture that is compatible for international usage. As such, all you would need is the correct bulb, the ARRI CP89 Lamp (650W/220V), B&H # ARLF650X, as well as a plug adapter to convert the US 3-prong plug to the plug used in your country. You did not indicate in which country the light fixture is to be used, so I cannot make a recommendation for a plug adapter, but they should be relatively easy to find.

Q: 10. Is this the standard Tungsten Bulb for an ARRI 650 fresnel?

A: Yes
