Ah i found it.
This is a citation from a google search on footcandles:
Phalaenopsis 1000-1500 fc Never exposed to direct sun light.
Paphiopedilums 1000-3000 fc Expose to only early morning sun.
Miltonia 1000-3000 fc Keep in diffused light.
Odontoglossums 1500-2000 fc Expose only to morning or evening sun.
Cattleyas 1500-3500 fc Give plenty of light without burning their leaves.
Vanda 1500-4000 fc They like strong light, full morning sun.
Oncidiums 1500-4000 fc Same as above.
Dendrobiums 1500-4000 fc Same as above.
Cymbidiums 7000-8000 fc Give as much light as possible without burning the leaves. Provide lower light (2000-3000 fc) when flower spike appears.
vandas need between 1500 and 4000 footcandles. Lucky for me I don't own Cymbidiums
they need even more!! Ill propably get away with it if I have to believe this. Offcourse a personal experience is still welcome. Thnx for the quick reply.
