I have a load of extra low voltage IKEA lamps, each with its own chunky plug-transformer.

I recently moved to a house with a 5amp lighting circuit with the small round-pin plug sockets, controlled by a light switch.

I don't really want to replace every 5a plug socket with 15a square pin variants (not least because I don't want to accidentally plug anything into them other than lamps).

Is there any way to adapt the ELV lamps to use the 5amp sockets?
