Im replacing 3 downlights in my newly refurbished built in wardrobe and they are robus 240v gu10 led's(were previosly g4 run on a transformer) but until now ive overlooked the fact that the feed that wS used and will be re-used(hopefully) was run from a wall circuit not from a lighting circuit. How big of a problem is this? What are the implications? Does it need a fused spur ? The feed was wired from an old single socket , bodged through a gap broken out of the casing-i changed this to a blanking plate , sunk the cable so it came out of a push out hole in the top of the pattress and ran new twin and earth to the wall under metal trunking and left it long with the end in a connector block in a chockbox until i had built my wardrobes, now im worried its not quite suitable and im risking a fire etc ?
