Transform your Christmas tree into a stunning centerpiece with these 6.6FT 400 LED Waterfall Lights. Designed to fit 5-7FT trees, this cascading light set features 16 hanging strings with 25 LEDs each, creating a beautiful waterfall effect that drapes evenly from top to bottom. The 9.8cm top ring makes installation simple—just loop it over the tree top and the lights fall perfectly into place. With a 5M extension cord, you have plenty of reach to position your tree exactly where you want it. Say goodbye to tangled wires. The flexible material resists tangling, saving you time and frustration during setup. USB compatibility means you can power it from multiple sources—wall adapters, power banks, or laptops—making it ideal for both indoor and outdoor tree decorating. Take full control with the included remote. Choose from 4 brightness levels (25%, 50%, 75%, 100%) and set the 6-hour auto-off timer for energy-saving convenience. The built-in memory function remembers your last lighting mode, so you never have to reset. Eight dynamic modes give you endless options—combination, waves, sequential, slow glow, chasing, slow fade, twinkle, or steady on—to match any mood or occasion. Built waterproof and low-voltage, these lights withstand winter weather while staying cool to the touch for safe household use. Just keep the USB plug dry. A reliable, hassle-free way to brighten your holiday season.
