Low voltage lighting
-
Can anyone tell me what the point of this is? I've just moved into a new house and three of the bathroom lights won't work. Reason being that in the path to each is an inline 12v 60VA transformer which is blown. The bulbs are 20w, so why not just use mains? They're in the ceiling so I can't see bathroom safety being the point. Just more to go wrong.

It's a Elf & Softy thing: Bathroom lighting regulations[^] - it's easier and cheaper to use low voltage than buy high-IP rating fittings.

Thank you. That explains it, regulation. Madness.

Me, all the timeI'll get back to you about that next week - if I'm not in hospital.

I don't know what the wiring regulations are in UK. In WA (Western Australia) all houses require residual current devices (RCD's) on all circuits so the use of 12v lighting has nothing to do with safety. 12v Halogen lighting became a fashion because of the light quality and the ability to shoot beams to wherever desired. They generate a lot of heat and are responsible for many house fires particularly when covered in the ceiling by roofing insulation. These are now being supplanted by 12v led lighting which is way more efficient and does not generate so much heat. Even though the globes may be very alike halogen 12v uses AC while LED 12v uses DC.

I once got an advice from an electrician, he said that halogen lamps breaks very quick when they are directly connected to mains (here 230-240 Volts). The general advice was to use the 12 Volt lamps, and a transformer. The lamps lasts forever. But the transformer may break, especially if it's too close to a halogen lamp. The transformers can't take too much heat.

It does if the lights are in the bath or shower and may be exposed to accidental immersion. If not the 12v is not mandatory but RCD may be.

Here' in sunny Qld it's illegal to do any wiring if you're not an electrician - but if it's low voltage you can go for it - so I think some houses wire up with low voltage so they can DIY (our previous house did). Bloody silly idea if you ask me

I didn't expect a section called "IP Numbers" in the electrical wiring guide. Maybe that's because English is not my native language. :) Still, I find this quite funny:
On reffered page:
Equipment with no IP number must not be used in Zones 0, 1 or 2, or in any other wet or damp location.
