grumbler said: The transformer power has to exceed the total power of your bulbs, but beware that some transformers have also minimum power limitation.

Also check what current the bulbs need - AC (alternating) of DC (direct). If (unlikely) they aren't compatible with both (i.e. aren't  AC/DC) make sure that the transformer provides what they specifically need.

And do get a transformer that provides full isolation between input (240V) and output (12V ?).

Some will drop the voltage, but are connected internally to the mains side - This could potentially give you a nasty shock or even kill if you were to touch one of the low voltage wires.

This is what I'm looking at doing, you can see they have a Valve light switch to the left middle. Ive looked online and can't find anything to purchase. 

Which is why I wanted to make one. Now I just need to figure out how to wire it properly. 


Kind regards

That is a thing of beauty! What do you plan to store on the shelves?
