To male it SELV would involve feeding it through a transformer. Then fit suitably rated lamps. Fairly certain this is almost exactly what I wrote before!how do you make it selv? and what lamps woul i use?
For instance, we did a job in a swimming pool and the customer wanted these particular wall lights in a zone which could only have SELV fittings. The fittings were fed from 12V transformers in the roof space and we then used 12V BC lamps, which are exactly the same as 230V BC lamps, apart from they are 12V.
