Manufacturer description

The BlcTec Christmas Lights string stretches 174 feet with 500 LEDs on dark green wire, giving you enough length to wrap a tall tree, outline a roofline, or run a fence without daisy-chaining multiple short sets. It runs on a 29V output, below the 36V threshold BlcTec cites as the human-safe maximum, and carries UL certification, so the bulbs stay cool enough to touch around kids and pets after hours of use. Eight lighting modes cover Combination, In Waves, Sequential, Slow Glow, Chasing/Flash, Slow Fade, Twinkle/Flash, and Steady On, and the memory function holds whichever one you picked so…
