2025 UL 588 Market Survey Results for Decorative Lighting Strings (DGZZ)
As part of the UL Solutions Market Surveillance Program, we have recently completed a market survey for seasonal lighting products marked as certified to UL 588, the Standard for Seasonal and Holiday Decorative Products. The program is intended to verify that lighting strings are manufactured in accordance with the requirements of our Standard.
In all, 145 samples were purchased from the U.S. marketplace during the 2024 Halloween and Christmas selling seasons and tested according to ANSI/UL 588 Standard requirements. Samples were purchased from retailers and online stores, such as Target, Lowe's, The Home Depot, Walmart, Big Lots, Family Dollar, Shein, Temu and Amazon.
Results
Seasonal lighting products certified by UL Solutions to ANSI/UL 588, the Standard for Seasonal and Holiday Decorative Products, demonstrate a better/higher compliance rate than seasonal lighting products certified by other Nationally Recognized Testing Laboratories (NRTLs).
