You just finished decorating the house. Everything looks magical. And then—click—half the lights go out after a rainstorm. Why? Cheap lights with zero safety certification."
What UL and ETL Really Mean for Homeowners
When you're shopping for holiday lights, it's easy to focus on color, shape, and cost. But hidden beneath the twinkle is a critical detail that affects everything from performance to fire safety: certification.
UL and ETL are two of the most trusted safety marks in North America. Understanding what they mean helps you pick lights that are not only beautiful—but also reliable, weather-resistant, and built to last.
Let’s break it down so your lights bring only joy this season.

What Are UL and ETL Ratings?
UL (Underwriters Laboratories) and ETL (originally Electrical Testing Labs) are both independent safety organizations. They test products to make sure they meet North American safety standards.
That includes checks for:
- Fire risk
- Water resistance
- Electrical stability
If a light string is UL or ETL listed, it’s passed testing to ensure it can be used safely in your home or yard—even in wet, wintery conditions.
💡 Homeowner Tip: Look for labels that say "UL Listed" or "ETL Listed" – not vague claims like "safe to use"
UL vs ETL: What’s the Difference?
UL is the older name and more widely recognized, while ETL is often used by newer or cost-conscious manufacturers. But here’s the key: they both test to the same safety standards.
| Feature | UL | ETL |
|---|---|---|
| Founded | Over 125 years ago | Over 100 years ago |
| Recognition | More familiar to most consumers | Gaining popularity in home and commercial markets |
| Standards Used | Same (UL/ANSI standards) | Same (UL/ANSI standards) |
So don’t stress if your lights are ETL instead of UL—as long as they have a real, verified listing.
3. Why Certification Matters for Home Use
Lights that aren’t certified can:
- Overheat
- Short out in the rain
- Increase the risk of fire
You might save a few bucks upfront, but if a strand fails—or worse, causes damage—you’re left in the dark. Certified lights are tested to perform in all kinds of conditions, from cozy living rooms to icy rooftops.
How to Spot Safe Lighting
Safe lighting isn’t just about bright colors and sleek packaging. Look for:
- UL or ETL logos printed on the box or plug tag
- A listing number you can verify online
- Labels that clearly state "Indoor/Outdoor Use"
Avoid anything that says only "tested to standard" without showing who did the testing.
💡 Homeowner Tip: You can check UL and ETL certifications online before you plug anything in.
