I'm looking for some advice on a light fitting that went pop. It tripped the fuse and is no longer working and looking to understand what may be the issue.

I've posted a PIC below and have not removed the fitting but wondered if anyone can suggest what the problem may be. I.e. is the a separate transformer or fuse in the metal housing above the light that may just need replacing or is a completely new light fitting required?

Step one remove all bulbs and re-try. If MCB trips with no bulbs then likely requires a new power supply. I would think twice about repairing as today extra low voltage lighting is a real problem.

The so called electronic transformer is not really a transformer, the electronics mean often a minimum as well as maximum output. This effectively stops the use of LED lamps.

Other than the bathroom I would not use extra low voltage lamps. Using low voltage (230vac) allows much more flexibility selecting bulbs. It also means one bulb blows at a time you don't get all bulbs failing together.

Thanks for the response.

The light no longer trips. It doesn't work, none of the bulbs work but it doesn't trip the MCB when I switch it on.

I'm gonna take the fixture off tomorrow and have a look. I just wondered if there was a fuse or something inside the bulky bit that would just need replacing?

Likely it is a switched mode device with no user parts to change. Most auto shut down with short circuit and auto restart once removed. Likely G9 bulbs which can be got in a range of voltage and wattage.

I hate them as all too easy for some one to fit the wrong bulb.
