Flourescent funnies
Maybe someone can answer this question!
We have two standard flourescent tubes at different locations in our "conservatory". 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. Any explanations?! |

Is there a (safe) way of checking if this is indeed the case? |

If you have a multimeter, you could measure the voltage between live and earth when the light is off If you get mains, then the live is live! |

The large fields generated by them will activate a fluorescent lamp slightly, and your finger will provide an earth and concentrate the field. Andy |

Andy 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. |

We have two standard flourescent tubes at different locations in our
"conservatory". 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. Any explanations?! You're crazy. That's the explanation. Creeping round your conservatory in the dark stroking light fittings indeed. People like you should be locked up. |

The other one doesn't but if I tiptoe and touch either of them, the area near and around my fingers will glow. 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 delayed reradiation. 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. |
