LIGHT -- How much is too much?

Soooo I'm thinking of moving these guys outside to get some more light.



According to First Ray's calculator, on a clear sunny day with no obstruction, the light intensity max would be about 9800 FC.

If I put my catasetums outside, what's the best way to ensure that they get the most light, without slowly acclimating them and risking them being burned by the sun? If I put up a 60% shade cloth above them, to cut the sunlight to 4000 FC at high noon, would this be safe, or could that still burn them?
