I can tell you we had a situation a few month ago where a couple of
lights in a parking lot (sodium vapor, I think) were emitting enough
interfernece to cause problems for a cell site receiver setup, atop a
5 or 6 story rooftop, less than 1/4 mile away. So, that would be 850
MHz, ~1,000 feet, and the receivers used at modern cell sites are
"very" sensitive. Active gain and filters, etc... May not be the
same as your situation.

Get an oscilloscope and wave the probe around the lamp fixtures.
I've seen impressive amounts of 40 KHz crud around flourescent lamp
fixtures.
Why does it matter? Is this one of those EMI-causes-cancer things?

The reference thread, in a hydroponic grower's forum, was a banner
suggesting that the EMI was detectable by drug enforcement
organizations.

As a possibly interesting aside -- when shooting digital photography
at high speed without flash under flourescent light, the white balance
will shift slightly according to where in the 60 cycles the light
source is at, at the exact moment the shutter opens. I don't know if
this is the case with sodium vapor lights? I suspect it would be.
Ditto for mercury vapor lights, although that would occur a much
higher K temp, and perhaps not as noticable of an effect (at least,
not in a photograph).

Cops use thermal imagers, too, to spot buildings that are dissipating
a lot of power. Even if the meters are boogered, I bet the power
feeders get warm, too.

Yep, definitely the same. I have a metal halide that I use for various
things, and when photographing stuff I see this as a shift in the colour and
brightness of the small LCD display. Usually that gives me enough cues to
when to push the button. I still take a couple of pics to be sure though.

"Maybe" it is what Johnny would wish were "certain values of worked

Maybe you should experience "certain values of being worked over".
