General description Whether your display is indoor or outdoor, these firefly fairy lights make decoration a breeze, thanks to having more LEDs per metre than typical string lights and the bulbs being spaced closer together. With a 5.1m lit length, these lights boast a soft flickering effect that's perfect for creating a magical lighting display. The dark green cable blends seamlessly into the green foliage of a Christmas tree, ensuring the focus stays on the LEDs, which are available in either white, warm white, or white with warm white. Your lights are also supplied with a generous 5m lead cable from the plug to the first light.
