Lots of miniatures to choose from. I have catt hybrids, most of them with cernua in the parentage, that don't grow more than 10 cm tall. They do spread, though!
I also have a lovely variegated mini dendrobium that is hugging the back wall of my gecko terrarium. It's maybe 25 cm from LED lights, and it's doing well.
You can also put in purple-leafed phals, they tolerate higher light levels. I plant phals upside down, and they grow out sideways.
