For a light setup, I need to use a particular model of led stripes. Unfortunately, the stripe with the LED model I need has a width of 12mm (and is globally only available in that width), the mounting I need to use can fit only 10mm.
From an electronics point of view, I can safely cut 2mm off the stripe lengthwise, however this needs to be done precisely and must not vary (2.5mm would be too much).
What tool could I use to efficiently do this? I need to cut ~10-15m of LED stripes.
Edit: The stripe is not enclosed, it is the plain PCB-only type.
Edit 2: The stripe is flexible, with one centered 5050 LED, the cut needs to be done on one side.
