Thank you winston1
So would i best with a set up like this from ebay:
http://www.ebay.co.uk/itm/2x-LED-Under-cabinet-Strip-Lights-12w-LED-12v-Driver-/250900789956?pt=UK_Home_Garden_Night_Lights_Fairy_Lights&var=&hash=item3a6ada3ac4
Then go straight from the ceiling light into the driver...
In the downstairs toilet my wife would like to place LED strip lights around a boxed shelf. I was wondering if i could wire into the lighting down to a hidden plug. From there connect to transformer for the led stripe light (30cm only). So when you turn the light on also the shelf lights up...
