As a globally recognized independent organization, UL sets the bar for product safety and performance across various industries. With over 60 laboratories worldwide, UL rigorously tests and certifies products to ensure they meet stringent safety standards. 

Understanding UL certifications is crucial for making informed decisions when choosing lighting fixtures for residential, commercial, and outdoor spaces. Let’s delve deeper into the difference between UL listings and what they mean for lighting fixtures in dry, damp, and wet environments.

The UL Listings Catalog:

The specific labels and markings vary depending on the region where products are manufactured. Detailed information for the Asia Pacific, Europe, and Latin America regions can be found on their website. Below, we’ll explain the major UL marks used for products manufactured in North America.

UL categorizes products as Type L or Type R, and their website features a convenient Product iQ database for confirming which one is applicable. Type L products display a UL Mark with an issue, lot, or serial number, while Type R products contain a marking with a control number or fixed 4-character number associated with a UL file number.

  • UL 508A – Standard for Industrial Control Panels
  • UL 9560 – ANSI/CAN/UL Standard for Energy Storage Systems and Equipment
  • UL 969 – Standard for Marking and Labeling
  • UL 142 – Standard for Steel Above Ground Tanks for Flammable and Combustible Liquids
  • UL 1703 – Standard for Flat-Plate Photovoltaic Modules and Panels

Just like UL 9560, certain standards align directly with U.S. standards upheld by the American National Standards Institute (ANSI). Due to this frequent overlap, there exists a continual process of review and updating to incorporate the latest requirements into all standards.

UL Listings for Dry, Damp, and Wet Locations

1. Dry Locations:

Primarily found indoors in above-ground spaces, luminaires with a “Dry Locations Only” rating are suitable for areas unlikely to encounter moisture. These locations encompass various indoor settings such as kitchens, dining rooms, offices, and hallways. While intended for dry environments, UL permits their use in spaces with occasional dampness, provided adequate ventilation prevents moisture accumulation.

2. Damp Locations:

Designed for areas regularly exposed to moisture and condensation, luminaires rated for damp locations offer enhanced protection for their electrical components. Common applications include laundry rooms, bathrooms, and covered outdoor spaces like porches. Despite their resilience to moisture, direct water contact is not advisable.

3. Wet Locations:

Luminaires labeled as “Suitable for Wet Locations” are engineered to withstand direct exposure to liquids, ranging from drips to steady flows. These fixtures find application in outdoor settings such as gardens, walkways, and signage installations. Sub-markings further specify their suitability for various degrees of water exposure, ensuring safe usage in diverse environments.

Choosing Lighting Fixtures With UL Certifications

Opting for lighting fixtures equipped with a UL marking (or other reliable marking) suitable for their intended application enhances the safety and longevity of your lighting system. Various other markings may exist, depending on installation methods and permitted or restricted locations. However, understanding the significance of UL dry, damp, and wet ratings significantly contributes to making an informed decision.
