UL 2749:2019 PDF Download

UL 2749:2019 is a standard that specifically addresses the requirements for LED drivers used in seasonal decorative lighting applications, as well as non-integral LED lighting strings. The standard applies to LED drivers that are used in conjunction with LED decorative lighting, such as string lights used for holiday decorations or other seasonal lighting purposes.

One key aspect of the standard is the definition of a non-integral lighting string, which refers to an LED lighting string that is provided with one or more fittings that do not conform to a standard NEMA configuration. This means that the lighting string may have custom or specialized fittings that are not commonly found in typical lighting installations. The standard provides additional requirements that must be met for such non-integral lighting strings.

It is important to note that this standard does not replace or override any existing standards for LED drivers or lighting strings. Instead, it supplements the requirements outlined in the referenced standards, ensuring that LED drivers used in seasonal decorative lighting applications and non-integral lighting strings meet the necessary safety and performance criteria. Compliance with UL 2749:2019 helps to ensure that these products are safe for use and function properly.
