Well, whether or not it is related to L. Miss Wonderful, it is certainly wonderful anyway.
Yes, it's hard to compare light levels. You have more air pollution up there, and a lower sun angle all year so your sun is much more gentle. You also have longer days in summer than we do, and shorter days in winter.
I'm gradually getting more brave about the amount of sun the orchids get. Doing ok with the Vandas and Brassavolas, but the Catts tend to get sunburnt easily. Just have to ease them slowly into the right situation, and then keep up that amount of light. It seems as if I am constantly moving orchids around to keep them in good light. I also have Aluminet shading the west facing side of the pool cage. That has worked well over the summer, but is coming down tomorrow, and I'll see how bright the light looks in the afternoon then.
As Jim noted above, today was surely not our typical sunny Florida day. Gloom and drizzle pretty much all day!
