Thanks everyone!
I have a plastic box roughly attached to my AI Prime HD now with some photographic light diffusion over it. (Opal for any of you filmmakers out there) The spread and shimmer are helped greatly by this but agreed that the PAR and intensity is absolutely effected, if not only a little.
What I'm more interested in is using the 3D Reefing diffuser to block out light spill onto my floor and walls and generally make the viewing experience a bit better. Has anyone had one of the 3D Reefing diffusers or can speak to them as a company/provider? I just found it odd that I couldn't find any threads of people using the diffusers on R2R. I would have thought someone would have picked one or two up by now!
Thanks again!
