Some of these effects are already known but some of them arent to me. Like the Wooden bench top.

I am using a Fluke 87v meter with 4 foot probes placed a foot from the wall. This picks up the 60hz house wiring. Both probes just lay on the bench not connected.
 
 Fluorescent light off mode. Just the Em field from the house wiring being used to pick up Voltage along with any Voltage that the meter may introduce from its battery.

With the light off and meter turned on I have 8Mv.
Placing one finger flat on the bench with no pressure in front of the probes the Voltage rises to 50.8 Mv.
Placing my hand flat on the bench with no pressure in front of the probes  the Voltage rises to 63.4 Mv.
As I increase the distance from the probes with my finger or hand on the bench the Voltage decreases as expected.
If I apply pressure with either finger or hand the Voltage rises slightly.
All this applys to both the top and bottom of the bench.

 
Fluorescent light on mode. Both House wiring and fluorescent light contribute to Voltage.

No finger or hand on bench the Voltage is 23.8 Mv.
With hand flat on Bench the Voltage is 97Mv.

Copper wire mode #1. Fluorescent light is on.

I hooked the + probe to 10 feet of #14 bare copper wire. The Negative just lays on the bench.
The Voltage on wire is .76 Volts.
When I grasped the wire the Voltage rose to 1.85 Volts.

Copper wire mode #2. Fluorescent light is on.
About 5 minutes later I turned the meter back on.
Voltage on wire was 1.02 Volts. Grasped wire and Voltage rose to 2.06 Volts. Let go of wire and placed hand on bench and Voltage dropped to .577 Volts. Turned off meter.

About a half hour later turned meter back on and grasped the wire and the Voltage was 2.30 Volts. I then disconnected the Negative probe from the meter and the Voltage dropped to 420 Mv on the Copper wire.

 Im seeing the wire charging up a little over time. The electromagnetic fields introduced into the meters circuitry, probes,bench top (cellulose), from the 60Hz wiring, along with the electronic ballast em field and frequency seem to be doing this. Thats a lot of stray fields fluctuating in intenisty,area and time. I thought about Jennas joule thief experiments with pulsed dc. I would think Every little wire,component lead,and surrounding enviroment would affect each other in the same manner until a balance is maintained.

 

Your pic describes a battery run meter??

Yes. Its a Fluke 87v true rms meter. Heres the specs of the meter.

I did this in my garage and yes the 60hz signal along with the voltage stops when the breaker is off.
I have to back the meter off to about 3 feet from the wall before the 60 hz Ac signal starts to rapidly fluctuate. The amount of Em radiation in standard house wiring has been known for years. Its quite a bit but I guess they consider it safe.

Electronic ballasts can do strange things. Ive had to troubleshoot multiple sets of lights on the same circuit where they either didn't work or only a few worked. Its a pain to track down as even a light that is working can have a bad ballast. I dont know myself as why this happens. I suspect some kind of frequency feedback.

 What caught my attention the most was the wooden bench top&bench bottom and the distance of the extended Em field through it from the probes and/or the ballast. Plus the charge that seemed to be induced into the wire.

@IotaYodi

I would also like to thank you for your investigation into this question. This basically confirms that anyone doing low voltage OU works will have to take this into account, as would any other serious researcher having to work with blind studies, placebo comparisons, etc.

Another member @EMDevices is presently showing something in the same line that you may find interesting. It is located here.

Thanks again.
