UK Security Light Problem.

[scaramander]

Ran a security light off a fluresent light in kitchen.
Used 4 port supply push in wire connecter.
Earth and neutral wires connected inline to existing terminal blocks.
When I turn "OFF" bathroom fluresent light after use, the security light turns on.
What's causing this please?
Thanks!!

On a different tack - might the security light be seeing light emanating from the bathroom?
It's presumably supposed to respond to IR from a person, and/or movement, but if it was detecting 'dusk' when the bathroom light goes off, might that switch it on?
Masking the detector should show one way or the other ?

The light is outside my kitchen door overlooking back garden.
Bathroom is some distance away.
Thanks for reply!

Is everything back fully functional

Prob a simple answer I guess

It looks like the chassis tag on the fluorescent is no longer connected to the terminal block ?

In the absence of many obvious answer

If everything is in order with the installation wiring and the new pir light wiring

I would be checking the switch terminals and probably checking if the issue occurs with an incandescent bulb connected at the bathroom

Seen something strange happen before switching off fluorescents

More than likely the answer is more obvious than that though
