Low-voltage halogen question

[blueST]

The title should say Low-voltage... One of the halogen down lights in our bathroom has stopped working. I'm a bit puzzled as I guessed that they would all be off a single transformer. On yanking the wiring out, this small block wrapped in tape appeared. What is it and could it be causing the fault?

Before anyone says, I have tried a new bulb!

Need to pull more wiring out, the transformer will be before that connection. Better to swap those out for mains powered fittings.

I'm thinking (hoping?) that black block wrapped in blue tape is just a connector.

Seems a bit bulky foe just a connector, but I'll get into it properly tomorrow and see what's what. Hopefully just a loose terminal.

MR16 is a truly horrible bulb standard, runs hot as hell and consumes a lot more electricity than LED. You’re better off in the long run to bite the bullet and swap them for GU10 fittings, especially when decent units from the likes of Aurora are under a tenner each.

If you keep pulling on the wires if you’re lucky there will be a single transformer for each luminaire and attached to that will be the mains cable loop. If so it’s very easy to change the unit.

If you’re unlucky then you might have multiple MR16s attached to a single transformer in a kind of star layout. That is a bit more of a fiddle to replace as you need to get a new 240V loop to each outlet and then connect it all up.

I can only imagine that the block in your picture is a connector as it looks like the low voltage pair coming out the other side, which will go back to the (as yet unlocated) transformer.

Fit these and forget. I fit hundreds a year zero call backs, as stated don’t waste any more time on what you have.

Problem identified! The transformer was tucked away just inside the ceiling and is dead. 0v across the output terminals. 4x Ansell LED replacements ordered.

And that little box in the photo was just a housing for terminal block.

You can get MR16 bulbs in 240v AC format now - those 12v transformers seem to have a habit of overheating and quitting in my experience.

Bit if a hitch. Picked up my shiny new LED downlights earlier, come to fit them and discovered there's no earth conductor in the wiring. These new fittings are not double insulated and need an earth. GRRRR!
