Bemco Jews row SW18 is a very good Electrical wholesaler who will provide you with any technical information you need to help choose the right product for you . It’s just off the big roundabout a slip road before you cross Wandsworth Bridge . Hope that is helpful
We’ve had the same Collingwood lights for nearly a decade now without any problem. It was a bit of an investment at first but has proven to be a very good value one. We recently added one additional fence post light…. Same model, same finish.. and it blends in seamlessly… the decade old ones look as good as new. https://www.collingwoodlighting.com/en/ ... r-lighting
