According to Orchidwiz:
Laelia purpurata var. carnea : 2500-3500fc
Cattleya aurantiaca : same
Cattleya bicolor : same
and
Oncidium ornithorynchum : same, but filtered/diffused light, no direct midday sun
Hope that helps, I don't grow any of these. I'm surprised that the Onc needs that much light! I would have thought that it needed much less light than that.
