I bought a 5 metre one from Aldi a few years ago. You were supposed to be able to cut it and use the supplied connectors for power connection but could never get it to work. But, careful scraping of the insulation to expose the copper conductors and then soldered wires directly. All the kitchen cupboards now have internal illumination, been working fine for 5 or 6 years directly from 12 volt with no failures.
