These LED tree lights are specifically designed for decorating your Christmas tree and create a pleasant atmosphere. The lights consist of 500 LEDs, designed with 8 different effects: a combination of all the effects, slow-glow, twinkle/flash, waves, chasing/running water, sequential, steady on and slow fade, which beautifully lights up and creates a magical holiday atmosphere. This lovely Christmas decoration is water-resistant, making it suitable for both indoor and outdoor use. You can easily place this decoration onto the top of your Christmas tree, and its light strings naturally drape to the floor. The lights are a real eye-catcher, especially in the evening, and they also serve as a cosy source of ambient light. While not in use, these LED lights can be easily stored for the next holiday's use. Note: The included USB is not waterproof, so this part has to avoid water. However, thanks to the 10 m cable, the item can be used outdoors as the cable and product are water-resistant. Important Note: The Christmas tree and baubles are not included in the delivery. The product has a USB connector, but the certified 5V USB power source is not included. - Berkfield Home Tree Lights with 500 LEDs Cold White 500 cm Indoor Outdoor
