Hi,

I'm looking for some advice if possible regarding a project that I'm trying to complete. I have some mini lighting (single LED) that at the moment runs from 3xAAA batteries (4.5v). I've done some testing with the batteries in and I'm getting a supplied power of 4.66v @ 122mah from the batteries into each unit. I want to change from batteries to mains supplied power via a 4.5v transformer. Firstly, is this possible to do and secondly, what sort of transformer can I use? Secondly, I want to string a load of of these lights together to all run from the same switch - should these be in series or parallel? I have spotted a 4.5v, 600ma transformer (DAGNALL ELECTRONICS | D3613 | Transformers & Accessories | Electrical & Circuit Protection | Farnell UK). Is this suitable? How many lights would I be able to use from this unit?

All advice very greatly appreciated.

Ben
