The previous owner of my bungalow (aka the bodge master general) placed four low voltage spots in the ceiling of the lounge (in doing so he managed to cut through one of the joists). These have never worked properly (some never lit up, the rest would turn themselves off at some point). Now they don't work at all, and hitting the switch has the effect of tripping the light circuit. So I want to replace them. Should I go for low voltage or mains ? Also since the guts of them are in the loft, what to do about the insulation ?, and just for good measure, I want to board the loft
Suggestions please.
