Our custom-assembled vintage-style decorative cord sets are not currently listed with an electrical testing organization (UL, ETL), however they are assembled entirely with UL and ETL listed components. Both plugs and receptacles are ETL listed, and the sockets and wire are both UL listed and over-rated when using our Tru-Tone bulbs.
We don't yet have the significant resources to fund and maintain the certification of our completed light sets, but our prominent manufacturing partner follows UL/ETL best practices, and electrically speaking, nothing is novel about their assembly.
Additionally, the very low power consumption and minimal heat output of Tru-Tone LED bulbs reduces risks when compared with high-power consumption incandescent light strings that are notorious for getting very hot.
We recommend only using Tru-Tone LED bulbs in our light strings for the best and safest performance, but they are rated for using incandescent lamps as well.
Our light strings operate with standard 110 Volts AC, so they are not toys. While tempting, please refrain from wrapping them around your loved ones (human or fur-covered) for photo-ops.
Both our Classic and Deluxe style of vintage-inspired Christmas light strings are the result of months of sourcing and testing to achieve a safe, modern-day version of the original Christmas tree light sets that our grandparents would approve of.
