No in the Uk ( im a UK citzen ) they dont have them. Some bullshit im pretty sure about they cant be approved for safety because of how our plugs are and they have different voltage.
However my friend, you can still use them and get them off Ebay im pretty sure.
Search Y splitters or Y adapters with the word 'Light'
there will be suppliers mostly from the US
Have fun and make sure u get good herb and be safe!
Peace
