Excellent assessment. Leaf burn is often from the overheating of the leaves.
To be honest, I used to grow many of my Stans in Cattleya light outside in Hawaii. I'm pretty sure the sunlight they got at that latitude was stronger than anything you can give your plants in summer! I found this to be species specific though, with the narrow leaved species (ie. oculata and its group) to more tolerant of high light conditions. The broad leaved species (ie. reichenbachiana) preferred darker locations.
What are you growing and is it possible to put them outside in summer, as said previously?
