Replacing MR16 transfomer

[vegasgo]

The MF300 is a toroidal transformer no? Not a JB.

I would suspect, a 300va transformer at that, thus powering 5 lights quite happily

Yes that's what it is, it obviously didn't like LED bulbs. I've swapped it for two LED low voltage drivers and I now have ten happy lights working.

Only the ones where people turn the ceilings into swiss cheese and through ignorance or stupidity do nothing to stop this sort of thing:

Mine isn't one of them, all dry in a well ventilated bathroom.

Toroidal transformers don't mind LED lights one little bit.

Mine isn't one of them.

How would you know?

only one half is accessible though the floorboards upstairs as the other half is under the roof.
