C. Walkeriana light question

[GardenTheater]

I got this Walkeriana in bud at our local orchid show in January 2013. I figured I could at least enjoy the blooms and scent before it pouted under my care. To my surprise it sent out 4 new pbulbs and now is growing roots. The leaves are horizontal and I wonder if it needs more light. It gets light from window and from grow light above it. Leaves did turned toward window where I suspect light is stronger. I'm wondering if I should move it gradually closer to the grow light. What do you think?

Here's the plant:
