The strip is made of flexible PCB material, and comes with a weatherproof sheathing. You can cut this stuff pretty easily with wire cutters, there are cut-lines every 1.3″/3.4cm (1 LED each). Solder to the 0.1″ copper pads and you’re good to go. Of course, you can also connect strips together to make them longer, just watch how much current you need!
Note: The operating voltage for this strip is 5V, do not use higher than 6V or you can destroy the strip.
