I'm gonna go out on a limb here and talk partially from knowledge and part from my butt

the problem with the florescent lights is not the light but the ballast required to run the lights which is kinda like a transformer for lack of a better word. When you have a ballast or transformer you have the potential for electromagnetic fields and or harmonics which are what cause problems with more sensitive electronic devices and these are even more prevalent when using magnetic ballasts like the older t-12's. effects from harmonics is going to happen in the actual circuitry like when you have your unit plugged into the same circuit as the lights. effects of electromagnetic fields are going to happen when your equip is just near the lights like shorter ceilings or like hanging down above your bench. that all being said one of the reasons its not as much of an issue in some cases than others is, the more modern lights use electronic ballast instead of Magnetic and the homes wiring if done properly is less susceptible to harmonics. now take all this with a grain of salt, YMMV. and anybody with more info on this feel free to correct me or add to it
