Hello. (newbie here, so sorry if this has been asked before). I have come up with a design for a lamp which I've been told would sell. I am keen to explore this. However, the lamp uses a GU10 ceramic base fitting. When I went to buy them in bulk, I came across a few pages trying to sell me a 'New Regulation' version of the GU10 ceramic base which uses three levels of insulation and a cord-grip. But this won't fit into the aperture that I have left myself in the design. Does anyone know if it's perfectly 'legal' to use standard GU10 ceramic bases? I would like to CE mark them. Thanks very much in advance for any help. (I have tried the BSI but they didn't even reply).
