Looking for very high light Micro Miniature Vandaceous species/hybrids?

[Ray]

I have grown ascocentrums in full sun (in PA) along side full-sized vandas, so would put them high on my list of recommendations.

I'm not surprised you saw burning with D. cuthbertsonii, as it's not really a high-light plant. If anything, I'd put it near-, to slightly below cattleyas in their requirements. The might tolerate higher, but must be kept quite cool to tolerate that.

As far as the schoenorchis are concerned, I'd put them closer to paphs levels.
