fluorescent light - Questions

[orchidbingo]

I'm using T8 basic shoplights with a mixture of 5000k and 6500k and I've had great luck reblooming catts, oncidium intergens and even bloomed an Ascocenda under these lights. First time to ever bloom a vanda type under lights.Just posted a picture in the Vanda alliance forum yesterday.
T5 are more efficient but I bought more orchids instead of replacing my old T8 set-up with T5's.

Good luck.
