If you're looking to use our Warm White Pico LEDs with your own 5V DC project (or if you like mounting LEDs using your own cables instead of ours), then this is the solution for you. Ten Warm White Pico LEDs mounted on a 0.5mm PC Circuit Board with cutaway tabs for easy removal. Two panels of five LEDs have solder points clearly marked (+ and -)-- just solder your own wires and free the LEDs from the panel with sharp cutters. Each LED is just 4mm in diameter. Works with any 5V DC power source.
