Actually they output HF AC normally which is why the cable length
becomes an
issue. Halogens get ruined on DC if they are not made for it with all the
stuff depositing at one end of the filament.

Hello Tim

They are not a transformer in the strictest sense of the word.
They are really a switched mode power supply that converts 230v AC down to
12volts DC.
The only problem, from my hobby point of view, is that they tend to
generate

loads of radio interference.
I deliberately bought what I would call proper transformers for my lights.
