We have completely gutted our ensuite, At the moment there are 4 mr16 12v 50w downlights dangling down. These need replacing as, at some point whilst removing ceiling for renovations, some of the lighting fixtures were taken off and have been lost in the rubble.
I would like to replace these lights with 4 mains 240v downlights as I believe there are more LED variety with mains GU10 lights as opposed to low voltage mr16.
My question is would is be a simply swap. i.e taking lighting fixture and transformer off and replace with mains voltage lighting fixture or do I need to replace the existing wiring as well? I ask this as the existing wiring consists of thin white wires and I thought it would have been the standard grey thicker lighting wire.
