The parts of the LED strip that you cut or sever cannot be reactivated or reattached. Therefore, it is important to measure the desired area accurately before you start cutting.
Tip: LED strips have markings at the points where you can safely cut them. Only cut at these indicated points to ensure the remaining part continues to work.
Plan your installation carefully to avoid wasting pieces of LED strip and make sure you have enough length for the entire area you want to illuminate.
