What is UL Listing

UL Listing is a certification mark provided by Underwriters Laboratories (UL), an independent organization that tests and certifies products for safety and performance. In the lighting industry, UL Listing is commonly used to indicate that a lighting fixture or product has undergone thorough testing and meets the specific safety requirements set by UL.

When a product is UL Listed, it means that it has been evaluated and found to comply with the applicable safety standards for fire safety and electrical safety. This certification ensures that the product is safe to be used by consumers in their homes and in places of business.

The UL Listing mark, denoted by the letters “UL” enclosed in a circle, is typically displayed on the tag or packaging of the lighting fixture. This mark serves as a visual indicator that the product has been tested and certified by UL.

Not all UL markings are the same. There are various UL listing and classification marks that manufacturers can use to indicate different aspects of safety and performance. For example, UL Listed signifies that the lighting fixture has met the safety requirements set by UL, while UL Energy Mark indicates compliance with specific energy efficiency requirements.
