Maybe someone can answer this question!
We have two standard flourescent tubes at different locations in our
When it is completely dark with both lights off, one of them faintly
flickers all of the time.
The other one doesn't but if I tiptoe and touch either of them, the area
near and around my fingers will glow.
Is it possible that the on/off switch is in the wrong lead i.e.
the neutral, instead of the live?
My recollection was that 230 volts was enough to get slight
fluorescence or to faintly glow a neon equipped pocket
screwdriver/tester just through body capacitance to earth? So if
the fixtures are sitting there (with switch in the off position)
at 230 volts potential????? An idea anyway? Terry.
Seriously, this is called phosphorescence, which is a different luminescence
to fluorescence. Fluorescence is immediate and what the tube is design for,
but many tubes contain material which displays some phosphorescence which is
I would love to see phosphorescence in the sea. In some areas the plankton
phosphoresces and at night leaves a ghostly trail in a boat's wake. And the
coral glows too. I know it happens in Hawaii, another good reason to go
there, as if I need another one.
Try Scotland. If you go to the western isles in Summer and climb up
something tall, you can see some wonderful phosphoresence. I suspect
the Gulf Stream is involved.
