Whilst looking at ronning a power supply for a sauna heater (Thanks for the answer adam151). I lift the floorboards to find my hall lighting has 6 low voltage down lights (each with its own transformer) on one switch but the lights are wired in series not parallel terminating at the last light using 1.5mm T&E. Is this safe?

They are not in series - if they were then they wouldn't work, as each transformer would only be getting 38-40V.

being pedantic is all well and good, but you haven't corrected the error of pete999's ways. He may go on believing his transformers are wired in series . . .
pete mate (where have i heard that before? answers on a postcard
) your transformers are wired in parallel. But they have been put on a daisychain circuit as opposed to a star circuit. This is perfectly safe to do before the transformer (as in this case), as the currents are quite low. After the transformer, things get a bit shaky if you have 6 lights because the current is quite high.
