hi all. Newbie to the forum although I have read it many times over the years. I want to swap some downlights in our hallway from MR16s with transformers to LED mains GU 10 Ansell iCage 230v fire rated ones. The MR16s have been attached to the mains by an old-fashioned looking junction box, below which is the transformer for each downlight. See pic! So do I retain the old looking junction box, or get rid of the lot and attach the new lights to the grey mains wire? And because they're iCage they need to be earthed. I think at present the earth may land in the old looking junction box. Hope this all makes sense!
