"Quality" of EM field... LOL that term just cracks me up. Just conjurs up an image of two hams "Yea your getting out but you sound like crap".
As I said in an earlier post that pepole have been living within RF fields for decades. They have been living in EM fields since the beginning of time.
Its all over the spectrum. Shall I post a picture of my Oscope set for a low voltage and show you the noise? Its so prevelant that its actually hard to block it out. You know that psssssssshhhhh you hear when you tune your TV to an unused channel? EM/RF signals. Oh and while were at it that TV of yours? Try holding the plug of an amplified speaker up to one sometime. You want to talk about strong EMI fields. "Dont sit too close or your hurt your eyes" my mother used to say.
Now there is no question that a strong RF field can cause damage it is after all how a microwave works. But there is strong RF fields in the order of microvolts and theres strong RF fields of 600watts or more in the radar range. Yes I know there different units of measure but trying to explain that would take too long. In a nutshell the EMI/RF field within a microwave is 10's of thousands time more powerfull than stray emi/rf from a compact fluorescent. Hell there are wall chargers that put out more noise than CFLs.
Remember all that hoopla about schools and homes being built adjacent HV transmission lines? Where has that gone?
Oh and I wanted to add about the headache thing. It is quite true that all fluroescent lamps 'strobe' one in good working order should strobe so fast you never notice. But some pepole are subsectible to strobing effects. Remember those epelipsy warnings on video games? So sure I believe that some pepole can get headaches from poor lighting. Properly working 'quality' flourescent lamps with the proper 'quality' ballast should strobe so quickly that even the most sensative amongst us would not be effected by it. Notice the word quality. There is a lot of cheap crap out there. The industry is driven by being 'inexpensive'. But once more addressing strobing this is where LEDs are superior ... but only with a 'quality' driver.
