Y splitters in the UK

hello to all, i was wondering if anyone from the uk has those Y splitter adapter things, if so were did u get them. i have a feeling they are not allowed and this is why i cant find them anywhere(but im not sure), as i have looked everywhere and i cant find them.

anyone know?

Just buy an extra lamp socket and twist up some wire yourself.

You can't get them. Have to make them yourself. I looked everywhere too. Couldn't even find them in the grow shop.

someone could make good money selling them in the uk,id have a few.....
