Sorry but i dont know what ELV lighting is but it was just one transformer for 3 lights.
They came from the rose to transformer. New lights dont have a transformer just daisychained with 1mm 2 core wire
Im changing them because....... im a woman lol and they dont go with the decor now.
:0))...
Im sure this may have been covered before but i cant find it. We are replacing bathrooms downlights that worked with a transformer with ones that are looped from the rose. Hubby has done this before and has looped the wires the right way but it has been tripping the switch and when not tripping...
