Having spent ages researching methods and types of lighting for the different elements of the installation and not quite finding what I need, it was suggested to me that a friend’s son may be able to help as he works with lighting and electronics.

My criteria was a compact, battery powered dimmable LED unit complete with on/off switch. Quantity required is around 20 units.

I am now getting the custom designed lighting units made to my specification and the bonus is they are far cheaper than any equivalent unit I could have bought in store or online.
