Too much light for Laelias and C. aclandiae?

[vmax3000]

I have this little group of Laelias (species, mostly, and one hybrid), a C. aclandiae and some C. aclandiae hybrids sitting in a SW facing window. The window is double glazed and the glass is frosted, well, puckered really, as it's a large bay window over the tub in my bathroom. I know these plants require a lot of light, but this may be beyond the pail. I turn a fan on during the day, which keeps their leaves cool to the touch. I have posted some pictures. I would love to get some input on lighting. Thanks, all.
