Oncidium/Odontoglossum spike growing over light fixture
 

I have a supermarket variety noid oncidium/odontoglossum hybrid on a bench in my garage w/ a 4x4' T5HO. It's spiking now and the spike is about 3 feet long. I had staked the spike but now it's outgrown the stake and the top 8-12 inches of the spike is now higher than the light fixture. My question is, do inflorescences need light to develop properly? Should I move my fixture up so the spike gets light, or will it bloom as long as the foliage gets the light it needs?

Thanks for the input.

I have an oncidium that has its spike growing over my light fixture and it seems to be doing fine. I think that as long as the foliage is getting the light it needs everything will be just fine.
