General Disarray
All other things being correct (temp, humidity, water, ventilation), what would you look for or what have you seen as a sign of too much light. Or is there such a thing.
I used to grow under lights and gave 12/12. I grew my multi paphs and phrags 6 feet underneath 1000 watt and that was way too much..I know a grower that grows cattleya and vandas like that and seems perfect. He also grows phrags four feet under T-5 flourescents (4 x 2 four bulbs) and they bloom and look healthy. He grows his dracula and masdies way off to the side (probably 8 feet away) where they only get bouncing light from the T5's.
Personally, I think they really like bright light when the sun is very low but shade when its overhead.
