These also have three poles, the third pole is just "the other way round". You can either make do with an adapter or buy a Swiss plug from a DIY store. Adapter solution: Brennenstuhl Fixadapter (type 12, Schuko) Problem here: Not waterproof. DIY solution may be splash-proof, but of course this voids the warranty...

There are T-connections after the transformer. There are also optional quick-connect extensions to increase the distance between the lamps. Power supply is via transformer

The item works with Hue Bridge and does not require an adapter, as far as we are concerned because it comes with a power supply in the box and connects to the Bridge wirelessly. But we recommend getting the bridge or lights as close together as possible during the initial setup so that they can be easily located and the firmware updated before placing them in the desired location.
