Quick Answer: Is ETL Acceptable Instead of UL?
Yes—an ETL Listed product can be a legitimate third-party safety-certified product in the United States. Intertek Testing Services NA, Inc. is recognized by OSHA as a Nationally Recognized Testing Laboratory (NRTL), and Intertek states that its ETL Listed Mark shows that a product has been independently tested and certified to applicable North American safety standards.
UL Solutions is also an NRTL and issues its own certification marks. The testing organization is different, but “ETL Listed” should not automatically be interpreted as “not really listed” or “less safe because it is not UL.”

| Question | UL | ETL | What It Means for You |
|---|---|---|---|
| Who issues the mark? | UL Solutions | Intertek | Different certification organizations |
| OSHA NRTL system? | Yes | Yes | Both operate within OSHA’s recognized product-safety testing framework when within scope |
| Does the mark mean the product was evaluated? | UL states representative samples bearing its mark are evaluated to applicable requirements | Intertek states ETL Listed products are tested and certified to applicable safety standards | The mark should correspond to an actual certification record |
| Follow-up production oversight? | UL certification programs include ongoing surveillance/follow-up | Intertek describes periodic follow-up inspections | Certification is more than a one-time marketing test |
| Automatically safe for every outdoor use? | No | No | You still must match the product to its marked use, environment and instructions |
| Does the logo replace code requirements? | No | No | Certification is one part of a compliant installation |
What an NRTL Is — in Plain English
NRTL stands for Nationally Recognized Testing Laboratory. OSHA describes an NRTL as a private-sector organization it has recognized as meeting legal requirements to test and certify products using consensus-based test standards.
OSHA’s requirements include the ability to test products to appropriate standards, controls for identifying certified products, follow-up inspections of production, independence from manufacturers and users, and procedures for handling findings and disputes.
One NRTL Certification Organization
UL is widely recognized by consumers, contractors and inspectors, but “listed” in electrical codes is a broader concept than the brand name UL alone.
Another NRTL Certification Organization
Intertek Testing Services NA is on OSHA’s current NRTL list. Its ETL mark is the certification mark homeowners are likely to encounter on many outdoor lighting and electrical products.
Which Safety Standards Matter for Landscape Lighting?
Landscape lighting is not one single product category. A 12-volt path-light system, a standalone low-voltage luminaire and a 120-volt outdoor wall light can fall under different standards.
UL Solutions specifically identifies UL 1838 and UL 2108 for low-voltage lighting, and UL 1598 for line-voltage luminaires. The right standard depends on the actual equipment design and intended installation.
For broader installation requirements, use the Landscape Lighting Electrical Code & Safety Guide, the outdoor lighting GFCI requirements guide, and the transformer mounting requirements guide.
UL Listed vs UL Recognized vs UL Classified
This is one of the easiest places to make a bad buying decision because all three labels can look “official,” but they do not mean exactly the same thing.
UL Listed
UL describes the Listed mark as applying to complete end products evaluated to applicable safety requirements. For a homeowner buying a complete transformer or luminaire, this is the kind of certification concept most people expect.
UL Recognized Component
A Recognized Component is generally intended to be built into a larger certified product. A component mark on an internal driver, relay or circuit board does not automatically mean the complete landscape-lighting product is UL Listed.
UL Classified
Classification generally means UL evaluated the product for specific properties, a limited range of hazards or use under specified conditions. Read the scope rather than assuming it is equivalent to an unrestricted end-product listing.
What UL or ETL Listing Does NOT Automatically Tell You
A valid safety certification mark is important, but it does not answer every question about whether a fixture is right for your yard.
- It does not automatically mean the fixture is rated for every wet or submerged location.
- It does not automatically mean the finish will resist salt, fertilizer, irrigation or coastal corrosion.
- It does not automatically mean any transformer can power any low-voltage fixture.
- It does not automatically mean the cable is approved for direct burial.
- It does not automatically mean the product can be installed near a pool, spa, fountain or other water feature.
- It does not replace manufacturer installation instructions.
- It does not tell you whether your local AHJ has additional requirements.
What to Verify by Landscape Lighting Product Type
↔ Swipe horizontally to see the full product checklist.
| Product | Certification Question | Outdoor Question | Compatibility Question | Common Mistake |
|---|---|---|---|---|
| Low-voltage transformer / power unit | Is the complete unit listed/certified for its intended low-voltage lighting use? | Is it intended for the mounting/environment shown? | Do output voltage/current/wattage match the system? | Buying by wattage alone |
| Path light / spotlight | Is the complete luminaire certified for its intended use? | Wet/damp/location suitability? | Voltage and power-unit compatibility? | Assuming “12V” means universally interchangeable |
| Direct-burial cable | Does the cable carry the required markings for its intended wiring use? | Is burial/environmental use covered? | Correct conductor size for load/run length? | Using indoor cord outdoors |
| Connector / splice | Is it identified for the intended low-voltage connection? | Suitable for wet/underground exposure? | Correct wire gauge and conductor type? | Using a dry-location connector in mulch or soil |
| LED replacement lamp | Appropriate certification/marking for the lamp? | Suitable for enclosed/outdoor fixture conditions? | Base, voltage, polarity and transformer compatibility? | Choosing by socket shape only |
How to Verify a UL or ETL Mark Before You Buy
The safest approach is to verify the actual product rather than trusting an online title.
- Look for the mark on the product or official product label. A logo shown only in a marketplace image is weak evidence.
- Read the wording around the mark. Listed, Classified and Recognized do not mean the same thing.
- Look for a control, file or listing identifier. Certification marks commonly include information that helps trace the certification.
- Search the certification organization’s product directory. Match manufacturer, model and product category.
- Check the geographic scope. U.S., Canada and combined marks can differ.
- Read the installation instructions. Certification applies within the product’s intended conditions of use.
- When something does not match, stop before installation. Contact the manufacturer, certification body or local electrical inspector.
Certification Red Flags on Cheap Landscape Lighting
“UL Approved” With No Actual Mark
UL Solutions states that “UL Approved” is not a formal UL certification designation.
“Built to UL Standards”
A manufacturer can claim design intent without the complete product actually carrying an NRTL certification mark.
Only an Internal Component Is Certified
A Recognized driver or power supply does not automatically certify the entire luminaire or transformer enclosure.
No Traceable Model or Listing Information
If the exact model cannot be matched to the certification directory, ask questions before assuming the logo is enough.
Indoor Certification Used to Sell Outdoor Equipment
Electrical safety certification does not erase environmental-use limitations. Outdoor, wet-location and burial conditions still matter.
CE Mark Presented as a U.S. NRTL Listing
A CE marking is not the same thing as a UL or ETL NRTL certification mark for U.S. product-safety listing purposes.
UL vs ETL on Landscape Lighting Transformers
The transformer is one of the most important places to verify certification because it connects to household line voltage and supplies the low-voltage lighting system.
Do not stop at “this is a 200-watt transformer.” Check the input rating, output rating, maximum load, intended lighting-system use, environmental/mounting instructions, certification mark and any limitations printed on the label.
For installation context, see the outdoor transformer mounting requirements, transformer sizing guide, and transformer wattage guide.
UL vs ETL on Landscape Fixtures
A listed fixture still needs to be used where its marking and instructions allow. A path light designed for ordinary landscape exposure is not automatically suitable for underwater use, pool zones or every in-grade installation.
Pay close attention to mounting orientation, supply voltage, cable/connector requirements, wet-location markings, replacement-lamp limitations and whether the fixture is intended to be used only with a compatible listed power unit.
For environmental exposure, compare the landscape lighting IP-rating guide and outdoor lighting gasket and seal guide.
What If an Inspector Questions an ETL Mark?
Start with documentation rather than arguing about logos. Intertek is an OSHA-recognized NRTL, and ETL is its certification mark. Provide the exact product model, listing record, applicable standard and installation instructions.
The local Authority Having Jurisdiction (AHJ) ultimately evaluates the installation under the codes adopted in that jurisdiction. A valid product certification is important evidence, but the AHJ also considers whether the equipment is being used correctly and whether local requirements have been met.

UL vs ETL Landscape Lighting FAQ
Is ETL Listed acceptable for landscape lighting?
ETL is Intertek’s product-certification mark. Intertek Testing Services NA is an OSHA-recognized NRTL. The exact product still needs to be certified for the applicable category, standard and installation conditions.
Is ETL less safe than UL?
You should not rank a product as less safe merely because it carries ETL rather than UL. OSHA’s NRTL framework recognizes qualified independent testing organizations, and OSHA says its recognition is not a relative ranking of one NRTL against another.
What is UL 1838?
UL 1838 is the Standard for Low Voltage Landscape Lighting Systems. It is one of the key standards associated with low-voltage landscape lighting.
What is UL 2108?
UL 2108 is the Standard for Low Voltage Lighting Systems. Depending on the equipment, low-voltage lighting products may be evaluated under UL 1838 or UL 2108.
What is UL 1598?
UL 1598 is the Standard for Luminaires and is used for many line-voltage luminaire products.
Is “UL Approved” a real certification label?
UL Solutions says “UL Approved” is not a formal designation. Look for actual UL certification marks such as Listed, Classified, Certified or Recognized Component, and understand what each mark covers.
Does a UL Recognized LED driver make the entire fixture UL Listed?
No. A Recognized Component is evaluated as a component intended for use within a larger end product under specified conditions. The complete fixture needs its own appropriate certification if a listed end product is required.
How do I know whether an online listing is really UL or ETL certified?
Look for the actual certification mark and model information, then verify the product through the certification body’s product directory. Do not rely only on marketplace wording.
Bottom Line
UL and ETL are different marks from different certification organizations, but both can represent legitimate third-party product safety certification. For a landscape-lighting buyer, the strongest decision is not choosing the most familiar logo. It is verifying that the exact transformer, fixture, cable or other electrical product is properly certified for its intended use, installed within its marked limitations and matched to the outdoor environment where it will operate.
