Is it possible to buy a second power unit + control unit and use the 2 strips in different rooms? I just needed 120 centimeters and the other 80 would be useless otherwise..
Look into Litcessory accessories, they provide adapters for cut segments. I used one of theirs for my kitchen above the cupboards, 1,5 meters, cut, extended with their extender to pass through the smoke extractor, then the other 50 cm. I also used a splitter and ran another extension from the top of the cupboard to the bottom and attached another 1,5m to the bottom of the cupboards.
