Opinions on power in a bathroom

There are several other OTS solutions with wireless switches, Philips Hue, IKEA etc.

 

Do the regulations have anything to say about a 24V or 12V circuit? Would this be another possibility for the light switch? Switch after the LED transformer.  Or do they say you can't have light switches unless they are switching mains for some reason?

12/24v is classed as SELV so is allowable in any zone. You can switch the DC side but beware your transformers will be always on and may not like it.

But modern transformers for charging our phones etc. are generally always on and if they are solid state don't really do anything until they are asked for energy - do they?

 

It's the old style power supplies based on wound transformers that are 'always on' and losing heat. There's precious few of them around these days - silicon being cheaper than copper.

 

Or am I mistaken? Are the transformers for LEDs still wire wound?
