Vandas Under Florescent Lights

[Captainjohn]

I grow a few vandas outside during the summer. I have now brought them indoors for the winter and put them under florescent lights.

I recently read in an orchid guide book that "vandas do not do well under florescent lighting". I have two questions: Why don't vandas do well under florescent lights and if this is the case, would I do better putting them in a bright, lighted window for the winter? Thanks..
