We normally only find them in Commercial and Industrial installations, these days.
Fluorescents aren't really used a lot in Domestic Installations, here.
BUT, the crux of the whole matter, is this.
Once found, the PCB fittings, are required to be disposed of (responsibly), I was told to throw them out at the local tip site, recently, by the owner of a factory, that was full of these bloody things.
even being in possesion of these materials,
carries a fine of NZ$200,000, being caught dumping them, carries a fine of NZ$500,000,
plus a 6month term of imprisonment.
Which avenue would you choose?.
I rang the Authorities and told them, not sure what happened, haven't heard back!.
Just as a sideline, it became illegal to have these PCB's in 1987.
