Expect them to be noisy.  Noise is radiated (at least) three ways -- 
from the tubes themselves, from wiring between the controller and the 
tube(s), and from power wiring. I've seen advice from the EMC community 
that it's possible to shield the fixture with screen wire to kill the 
wiring from the tube, and radiation from power wiring can be killed with 
a good common mode choke, using the measured data of Appendix One of my 
RFI tutorial as winding guidelines.
