There is a huge variability in RFI among various brands and models.  In 
theory, they meet FCC standards (Part 15? or maybe exempted as lighting 
equipment or because the switching rate is low enough or...), but that 
might be a pretty loose standard.

Some trial and error is called for. And, then, even if it's the same 
model, it might still be variable, as they change manufacturing 
processes and designs.

BTW, the noise is mostly carried on the power lines, and radiated from 
there, so perhaps some heavy duty RFI filtering (close to the lamp) 
might help?
