Ash, I'm commenting to bring this info you posted awhile
back, back up again, in case the guys were to busy to follow up on it or forgot about it.

@All,
Does a touch change what is happening inside the bulb or inside
the circuit to light the bulb or does a touch change what is
happening outside the bulb and outside the circuit to
to light the bulb or is it both?

Can anyone tell me in which direction the energy which lights
the bulbs flows?

I've seen touching on two videos now that causes a light
bulb to turn OFF. (there are probably more, I know of two)
This is a clue. Touching only "generally" causes the bulbs to light
or get brighter.
We have seen wood transmit a touch.
Has anyone been able to shield their touch from brightening a bulb?
A shield might be used as a funnel to focus energy?

Just
Randy
