I am going to be gelling some overhead fluos in a conference/meeting room this week. The room is used for a very particular type of video conference. I was called in to work on it because currently the people on camera are getting blown out by the overhead lighting.

For a mockup, I silked the ceiling with what amounted to about 2 layers of gridcloth and that gave a VERY nice look to the light and softened everything wonderfully. But firecode won't allow it because it blocked the sprinklers.

So I bought a roll of Rosco Tough Rolux with the idea that I'd use a sheet of plexi in the fixtures with the rolux attached to each sheet. I was just wondering how much light I am probably going to lose this way and the Rosco site was of no help.

(and no I am not going to only use overhead lighting. I ordered two dimmable flou fixtures that will be affixed at the front of the room to give some shape to the faces.)


Thanks in advance.

If you need to know before you get the product data, you could put a light through it and meter it or use a camera
to measure what you have for a stop with and without any diffusion.

Yea, that's where I am going to be it seems. Nothing like just putting a meter on it. Kinda makes me mad that Rosco don't just say what it is. I don't particularly care, I'd just like to know in advance if I am going to have to re-bulb.

Do the overhead fixtures have a frame and some type of diffuser? Cracked Ice, honeycomb, grid?? Why not remove all the existing frames and attach your diff to them, using paper tape? Certainly cheaper than having a plexi cut to fit.
