Q: 6. I apologize for double posting, but I have a few other questions about this product that I forgot to ask. That is, what is the speed ring diameter for this light? How many accessories can it hold simultaneously? (Scrims, filter frames, barn-doors, etc). How far from the light should I place my filters to avoid over-heating / setting them on fire?Also, regarding my first question: Can this light be safely mounted on a truss system? , I meant mounting it on a truss system using the baby receiver and a super clamp with a 5/8 baby pin.

A: The speed ring diameter for this Arri light is 9 -5/8. An example of such is the Chimera Modular Speed Ring for ARRI M8 and Zylight F8 B&H # CH9213OP, which can be used the the Octaplus and Video Pro Plus Softboxes also from Chimera. In terms of holding scrims, the T2 offers adjustable accessory brackets to allow you to hold either 2 or 4 scrims at a time. If using scrims with a gel holder, normally the gel holder should be placed in front of the scrims. As for hanging this light with a Super Clamp and a 5/8 baby pin, that would be possible if using a Manfrotto Super Clamp, B&H # MA035RL which has a maximum load capacity is 33.1 lbs.
