Thanks guys. Some peculiarities of what I'm asking: I'm not using shielded connectors nor cable. Just plain plastic RJ45 and UTP CAT6 cable. The question is if I should build a shield around the cable for the 40 feet that run along the fluorescent tubes and LED strips (and 4" apart). What do you think?

The most important thing is to use twisted pair. Belden’s “mediatwist” is bonded which means that the pairs don’t untwist at bends — that’s the single biggest way noise can get into the cable. 
 

The problem with shields is that noise from the transmitter can be projected into the receiver (and then loop back on common ground). The coupling can be capacitative.
