do you have the kind with the mottled leaves? It is possible that if you give them light up to the point where the mottling is prominent, then that might be the perfect light. I have one (a large one) and am trying this. They have thick leaves, and to me, this means "higher sun."
The only real difference you'll see based on lighting is that in lower light, roughly at the level a Phalaenopsis likes, you'll get larger and more colorful flowers, while at a higher light level you'll get smaller flowers. However, you still want to keep the plant in light less than what a Cattleya wants.
Good. Moved it to a little brighter window. I love this flower ever since someone compare it to a samurai in full gear. My husband has taught martial art for years.
