A 2 meter Lightstrip Plus Extension? Yes, yes it is!
These strips are brand new, never used or placed (fresh tape!) but open box and come from the regular Philips Hue Lightstrip Plus V4 (Bluetooth + Zigbee, latest version as of November 2023). They can be used as an alternative to the Lightstrip Plus 1m extension. The difference here is that there will be fewer connection points for long runs, reducing the number of failure points.
Note that the strip does not come with the power supply, or the controller, it is only the LED strip and cut point connector (one for each 2 meter strip) that is included.
The wire at the front of the 2m strip has been removed to reveal the 6 pins to make it pluggable as an extension into another strip (see pics).
