Some t5s are rated to produce constant light over the length of the tube (but I doubt the claims, as the above folks attest). I have best performance with 48" tubes over a 36" wide Orchidarium.

I don't do most Dendros or large, "floofy orchids". For me it's minis (like Angraecoides), Masdies, Paphs, and others that crept in somewhere along the line. See my orchid list for complete collection (usually not current.)
