These LED tree lights are specifically designed for decorating your Christmas tree and create a nice atmosphere. The lights consist of 150 high-powered LEDs, which are very energy efficient and emit a bright light. Designed with 8 different lighting effects: a combination of all the effects, slow-glow, twinkle/flash, in wave, chasing/running water, sequential, steady on and slow fade, it beautifully lights up and creates a magical holiday atmosphere. This lovely Christmas decoration is water-resistant and therefore suitable for both indoor and outdoor use. You could easily place this decoration onto the top of your Christmas tree and its light strings will naturally drape to the floor. It will be a real eye-catcher, especially in the evening, and also serves as a cosy source of ambient light. While not in use, these LED lights can be easily stored for next holiday's use. Have fun during your holiday with these LED tree lights! Please note that the Christmas tree and baubles are not included in delivery. The included USB is not waterproof so this part has to avoid the water, but thanks to the 5 m cable the item can be used outdoors as the cable and product are water-resistant. Note: The product has a USB connector, but the certified 5V USB power source is not included.
