Made with the extremely small 0603, Nano, size LEDs, this strip becomes the smallest LED strip made. We call it a ribbon of LEDs. The full strip is 21 inches long with 42 LEDs and less than 1/8th inch wide. It has an aggressive 3M adhesive backing for easy installation. The ribbon works with a 12 volt, DC current only. It can be cut at every two LEDs: A new set of wires can then be soldered to the remaining section. These strips are available in Pure White and Warm White. They are also sold in packages of individually cut lengths of 1 inch pieces, 2 inch pieces and 6 inch pieces. A perfect strip to illuminate small 1/4 scale and 1/2 scale projects as well as illuminating display hutches or those kitchen cabinets in your dollhouse.
