Over year ago I had 50W halogen downlighters installed in my kitchen. There are 12 altogether and each has its own transformer. Recently they have decided to stop working, gradually one by one and now there are none working. An electrician came round and said the transformers had blown...ALL of them?? and it was odd that the voltage reading he was getting at the switch was 57, not 230. He said that they were wired in series which was ok but that the whole lot would need replacing. Is he correct?
I would agree that for 12 transformers to blow seems a little unusual. At 2.6 amp I would have expected the trip to keep tripping as that's a lot of lights for one switch. I would go for low voltage instead of extra low voltage unless you suffer from voltage variations.
