Are Outdoor Christmas Lights Waterproof?
Why This Question Matters During the Holiday Season
As the festive season rolls in and homes across Lewisville light up with colorful displays, one concern often goes overlooked: Are outdoor Christmas lights waterproof? It’s a simple question that can have serious consequences if ignored. Whether decorating trees, rooflines, or backyard patios, using the correct type of lighting is essential for safety and durability, and a responsible choice for creating that perfect holiday glow.
At Bernardy Lighting LLC, we’ve seen firsthand how skipping this detail can lead to tripped fuses, ruined displays, or fire hazards. So, let’s explore how waterproof your lights are and what you should do to stay safe and festive.
Waterproof vs. Weatherproof – What’s the Difference?
One of the biggest misunderstandings in outdoor lighting is that waterproofing does not always mean safety in all weather. There’s a subtle but significant difference between waterproof and weatherproof lighting.
Understanding IP Ratings
The IP rating (Ingress Protection) determines how well a light fixture can withstand water and debris. For example:
- IP65: Dust-tight and protected against water jets (safe for outdoor use)
- IP44: Splash-proof (okay under covered patios)
- IP20 or lower: Indoor use only
If your Christmas lights don’t clearly show an IP rating of 44 or higher, they’re probably not suited for the outdoors.
What Type of Lights Are Meant for Outdoors?
Lights labeled “for outdoor use” are designed to handle rain, snow, wind, and changing temperatures. LED lights with sealed connectors and coated wiring are usually more durable and energy-efficient, making them popular in Lewisville’s unpredictable winter weather.
How Different IP Ratings Affect Outdoor Christmas Light Safety
When choosing outdoor holiday lights, the IP rating (Ingress Protection) helps you understand how well your lights can resist moisture and dust. Here's a quick breakdown:
| IP Rating | Water Protection Level | Suitable for Outdoor Use? | Best Use Case |
|---|---|---|---|
| IP20 | No water protection | ❌ No | Indoor decorations only |
| IP44 | Protected from water splashes | ✅ Yes (Light outdoor use) | Covered patios, doorways |
| IP65 | Resistant to water jets and dust | ✅ Yes (Moderate outdoor use) | Rooflines, fences, tree wraps |
| IP67 | Can withstand full water immersion briefly | ✅✅ Yes (Heavy-duty use) | Exposed areas, frequent rain/snow zones |
| IP68 | Fully waterproof and submersible | ✅✅ Yes | Ponds, fountains, and extreme weather areas |
This table helps you compare what kind of protection your lights offer, so you don’t just decorate beautifully, but safely too.
Common Risks of Using Non-Waterproof Holiday Lights
Let’s be real: it’s tempting to reuse indoor lights outside to save money. But here’s what could happen if you do:
- Short circuits from water exposure
- Tripped breakers or blown fuses
- Melted wires from overloading
- Fire hazards, especially on dry trees or bushes
- Total burnout of entire light sets
Worse yet, damaged cords or exposed wiring can be dangerous for kids and pets who play outside.
How to Know If Your Lights Are Safe for Outdoor Use
1. Check the Packaging
Look for labels that clearly state: “Outdoor Safe,” “Waterproof,” or an IP rating above 44.
2. Look for UL or ETL Certification
UL-listed or ETL-approved products mean they've been tested for safety by independent labs.
3. Avoid Extension Cord Overload
Make sure the power source and cords can handle the load. Wet cords = trouble.
Tips to Protect Christmas Lights from Water Damage
Even waterproof lights need a little extra care to last the whole season. Here's how to keep them shining bright:
Use Insulated Outdoor Extension Cords
Only use cords labeled for outdoor use — they’re thicker, more insulated, and can handle moisture.
Avoid Ground-Level Installs
Keep plug points off the ground to avoid puddles and standing water.
Use Weatherproof Covers
Protect plugs and connectors with plastic enclosures or waterproof boxes.
Consider Lighting Automation
Timers and smart controls help avoid overheating and let you manage lights remotely — something we specialize in at Bernardy Lighting LLC. Lighting automation adds convenience and helps prevent potential safety hazards by ensuring your lights are not left on for extended periods.
Go Pro for Complex Setups
From rooftops to large trees, if your display involves a lot of climbing, wiring, or custom installations, it's safer (and better looking) to call in professionals. Our Lewisville team designs and installs holiday lighting with safety and aesthetics in mind.
