Hello, unfortunately not from Philipps. But in Hornbach you can buy a T-piece for a couple of francs and only make a "small" change. It has a "tooth" inside and you simply have to take it away with a Japanese knife, for example. That's how I did it and it works. Greetings,

As I understand it, these are unfortunately not available individually. But each lamp contains a T-piece, if I remember correctly.
