Not every space in your home faces the same moisture conditions, and not every fixture is built to handle them equally. Whether you are selecting a pendant for a covered porch, a flushmount for a steamy bathroom, or a ceiling fan for an open deck, understanding UL ratings is one of the most practical steps you can take before making a purchase.
These ratings tell you exactly where a fixture can be safely installed, taking the guesswork out of choosing lighting for kitchens, bathrooms, outdoor living areas and beyond.
Understanding UL Ratings for Lighting and Ceiling Fans
Key Benefits and Features
- Safety assurance: UL Listed fixtures have been independently tested for electrical safety and fire resistance
- Location guidance: UL ratings tell you exactly where a fixture can be safely installed, whether in dry, damp, or wet environments
- Multiple certification paths: UL, ETL, and CSA marks all confirm a product meets the same national safety standards
- Confidence when shopping: Understanding the difference between UL Listed, UL Rated, and UL Certified helps you make informed decisions
- Code compliance: Choosing properly rated fixtures helps ensure your installation meets local building code requirements
What Are UL Listings?
UL Solutions (formerly Underwriters Laboratories) is an independent, globally recognized product safety organization that has been testing electrical products for more than a century.
When a lighting fixture or ceiling fan earns a UL Listing, it means the product has been rigorously tested against established safety standards and has met defined requirements for its intended use.
Most of the ceiling lights, wall lights, outdoor lighting and ceiling fans sold in the United States have been tested and rated by an independent product safety certification organization. Underwriters Laboratories gives these products a UL Listing, and Intertek gives an ETL Listed mark. Whether its UL or ETL depends on the product, and either rating can help you choose the most appropriate fixture for your needs. It is worth noting that UL is not the only certification body; ETL and CSA marks carry equal weight (more on those below).
The following ratings let you know where your lighting or ceiling fan may be installed (note that UL and ETL are interchangeable for this purpose):
UL Listed (for Dry Locations)
Often noted just as “UL Listed.” A dry location is an indoor area that is not normally subject to dampness. It may include a location subject to temporary dampness, provided ventilation is adequate to prevent any accumulation of moisture.
Dry Locations include:
- kitchens
- living rooms
- dining rooms
- bedrooms
- foyers
- hallways
- most areas in bathrooms
You can find UL and ETL ratings in the details section of any product page. If there is no UL or ETL listing mentioned, assume the fixture is suitable for dry locations only.
UL Listed for Damp Locations (Damp Rated)
Only lighting fixtures and fans marked “Suitable for Damp Locations” or “Suitable for Wet Locations” can be used in damp locations.
A damp location is an exterior or interior location that is normally or periodically subject to condensation of moisture in, on or adjacent to the electrical components of a lighting fixture or ceiling fan.
Kitchens, bathrooms and other rooms with large sources of water like sinks and showers can expose lighting fixtures and ceiling fans to moisture in the form of steam and condensation, even if the water doesn’t splash directly on the fixture. Think about the area right next to the kitchen sink when doing dishes, or a bathroom that stays steamy after a shower. A damp-rated fixture is ideal for these situations.
Indoor Damp Locations include:
- indoor pool areas
- utility rooms
- over bathtubs or showers in bathrooms (without risk of direct water contact)
Using Damp-Rated Products Outdoors
Outdoor damp-rated fixtures can only be used in covered, fully protected locations that are not directly exposed to water, even during storms.
Outdoor damp locations include covered patios and covered porches that are fully protected from water, even during storms.
UL Listed for Wet Locations (Wet Rated)
Only lighting and fans marked “Suitable for Wet Locations” can be used in wet locations, both indoors and outdoors. A wet location is an interior or exterior location in which water or other liquids may drip, splash or flow on or against the electrical components of a lighting fixture or ceiling fan.
Outdoor wet locations include:
- open-air decks and patios
- uncovered porches
- outdoor dining areas
- exterior walls, gazebos
- pergolas and walkways
Indoor wet locations include shower enclosures.
UL Listed vs. UL Rated vs. UL Certified: What Is the Difference?
These terms are often used interchangeably, but they carry distinct meanings.
“UL Listed” is the official designation indicating that a product has been tested by UL Solutions and meets specific, published safety standards. You will see this mark on the vast majority of residential lighting fixtures and ceiling fans.
“UL Rated” is not an official UL term. It is a colloquial shorthand that consumers and even some manufacturers use when referring to products that carry a UL mark. If you see “UL Rated” in a product description, the manufacturer most likely means the product is UL Listed.
“UL Certified” is a newer unified mark that UL introduced in 2013 to streamline its various certification labels. The UL Certified mark encompasses both the traditional Listed and Classified designations under a single, recognizable symbol. In practice, whether a fixture carries the classic “UL Listed” label or the updated “UL Certified” mark, it has been independently tested and verified for safety. Understanding these distinctions helps you shop with confidence, knowing exactly what each label means.
ETL and CSA: Other Safety Certifications for Lighting
UL is the most widely recognized name in product safety testing, but it is not the only one. ETL, administered by Intertek, and CSA, managed by the Canadian Standards Association, are equally valid certification marks.
All three organizations are Nationally Recognized Testing Laboratories (NRTLs) as designated by OSHA, which means they test products against the same published safety standards.
When you see an ETL or CSA mark on a lighting fixture or ceiling fan, it provides the same assurance as a UL mark: the product has been independently tested and meets the required safety criteria for its intended location.
Frequently Asked Questions About UL Ratings
What Does UL Listed Mean?
UL Listed means that a product has been tested by UL Solutions (formerly Underwriters Laboratories) and has met the safety requirements defined for its specific category. For lighting fixtures and ceiling fans, this testing covers electrical safety, fire resistance, and suitability for the location type (dry, damp, or wet) indicated on the label.
Expert Tip: When in doubt, check the UL or ETL rating listed in the product details on any Lumens product page before you buy.
What Is the Difference Between UL and ETL?
Both UL and ETL are marks issued by independent testing laboratories recognized by OSHA. UL marks come from UL Solutions, while ETL marks come from Intertek. The two certifications are functionally equivalent: both confirm that a product has been tested against the same national safety standards. You can install a fixture with an ETL mark anywhere you would install one with a UL mark.
Expert Tip: If a fixture carries an ETL mark instead of a UL mark, there is no need to hesitate. Both certifications hold equal authority under OSHA.
Can I Use a Damp-Rated Fixture Outdoors?
Yes, but only in covered, fully protected locations. A damp-rated fixture is designed to handle moisture from condensation and steam, not direct exposure to rain or water. If the outdoor area is an uncovered patio, open deck, or any space where water can reach the fixture, you will need a wet-rated fixture instead.
Expert Tip: A good rule of thumb: if rain could reach it, choose wet-rated. If only humidity or steam is a factor, damp-rated will do.
How Do I Find the UL Rating on a Light Fixture?
On the Lumens website, the UL or ETL rating is listed in the details section of every product page. On the physical fixture itself, look for the UL, ETL, or CSA mark on the label or tag, typically found near the electrical connection point. The mark will indicate whether the fixture is rated for dry, damp, or wet locations.
Expert Tip: Before installing any fixture in a bathroom, kitchen, or outdoor space, confirm its location rating matches the environment. The few seconds it takes to check can prevent a costly replacement.
When shopping for lighting or a ceiling fan for your home, be sure to review its UL Listing or ETL Listing to ensure it is the right fixture for your situation.
