How many of these would I need per shelf to grow phalaenopsis, and how high above the foliage should the lights be to light the space? What about for plants that need med/high light like mini cattleyas? I hope these questions aren't too specific. Thanks!

They are intended to be drop-in replacements (light wise) for T8 fluorecents, but I have no first-hand experience growing under either.
I would probably use two tubes per shelf, and 10"-12", maybe less.
