When shopping for outdoor lighting, you’ve probably come across the terms waterproof and weatherproof—but what do they really mean? Understanding these differences is essential to choosing the right lights for your outdoor space, ensuring longevity, and protecting your investment.
In this expert guide, we’ll break down the key differences between waterproof and weatherproof lighting, explain IP ratings, and help you decide which type is best for gardens, patios, commercial spaces, and other outdoor areas.
What’s the Difference Between Waterproof & Weatherproof Lighting?
Many people assume waterproof and weatherproof mean the same thing, but they serve different purposes when it comes to protecting outdoor lights from environmental damage.
- What is Weatherproof Lighting?
-
- Designed to withstand exposure to rain, humidity, dust, and temperature changes.
- Can handle occasional splashes and moisture, but not full submersion.
- Ideal for covered patios, exterior walls, and semi-outdoor spaces where lights are partially protected.
- Example: Wall sconces or ceiling-mounted lights under an awning.
💡 Best for: Porch lights, garage lighting, pathway lights in dry climates.
- What is Waterproof Lighting?
-
- Completely sealed against water penetration, making them safe for wet environments.
- Designed to be submersible or exposed to direct rain, heavy splashes, or extreme humidity.
- Used in pools, fountains, marine environments, or heavily exposed areas.
- Example: Submersible pool lights, waterproof LED strip lights for decks.
💡 Best for: Pool areas, exposed landscape lighting, marine-grade lighting.

Understanding IP Ratings for Outdoor Lights
When choosing outdoor lighting, look at the IP rating (Ingress Protection), which measures resistance to solids (dust) and liquids (water). The IP rating consists of two numbers, with higher numbers indicating better protection.
How to Read IP Ratings:
🔹 First Digit (0-6): Protection against solid particles like dust and dirt.
🔹 Second Digit (0-8): Protection against water and moisture.
Here’s what the numbers mean:
|
IP Rating |
Protection Level |
Best Use |
|
IP44 |
Splash-resistant |
Covered outdoor areas, patios, porches |
|
IP55 |
Dust & rainproof |
Gardens, pathways, exterior walls |
|
IP65 |
Water-resistant & dust-tight |
Floodlights, driveway lights, exposed areas |
|
IP67 |
Waterproof, handles full water immersion up to 30 min |
Pool decks, water features |
|
IP68 |
Fully submersible |
Underwater lighting, fountains, marine use |
🔎 Pro Tip: For general outdoor lighting, look for at least IP65 to ensure durability in rain and wind.
Which Type of Lighting Do You Need?
Choosing between waterproof and weatherproof lighting depends on where and how the lights will be used. Here’s a quick guide to help you decide:
- Lighting for Gardens & Pathways
✅ Best Option: Weatherproof (IP55 or higher)
-
- Path lights, stake lights, and low-voltage LED fixtures typically require protection from rain but not full submersion.
- Avoid placing lights in areas prone to flooding unless they are fully waterproof.
- Lighting for Patios & Outdoor Seating Areas
✅ Best Option: Weatherproof (IP44 - IP55)
-
- If your patio is covered, wall sconces or ceiling-mounted lights with an IP44 rating are sufficient.
- For exposed patios, opt for IP55-rated fixtures to handle rain and humidity.
- Pool, Fountain & Water Feature Lighting
✅ Best Option: Waterproof (IP67 - IP68)
-
- Fully submersible LED pool lights or floating solar lights need at least an IP67 rating.
- Underwater lighting for fountains requires IP68 for maximum protection.
- Security & Floodlights for Driveways & Exteriors
✅ Best Option: Waterproof (IP65 or higher)
-
- Motion-sensor floodlights and wall-mounted security lights need strong water and dust resistance.
- LED spotlights positioned in exposed areas should have an IP65 rating to endure storms and heavy rain.
- Coastal & Marine Environments
✅ Best Option: Marine-Grade Waterproof (IP68, corrosion-resistant)
-
- Seaside homes and docks require weatherproof and salt-resistant materials like stainless steel or polycarbonate.
- Marine-grade IP68 fixtures are ideal for withstanding saltwater exposure and humidity.
Choosing the Right Materials for Outdoor Lighting
The durability of your outdoor lighting isn’t just about IP ratings—the materials also play a huge role in ensuring longevity. Here’s what to look for:
🔹 Aluminum – Lightweight, rust-resistant, and ideal for most weatherproof fixtures.
🔹 Stainless Steel – Durable and corrosion-resistant, perfect for humid or coastal climates.
🔹 Brass & Copper – Naturally weather-resistant, developing a stylish patina over time.
🔹 Polycarbonate & ABS Plastic – Shatterproof and lightweight, often used for waterproof fixtures.
🔎 Pro Tip: If your outdoor lights will face constant moisture, avoid fixtures made of iron or untreated steel, as they tend to rust quickly.
Maintenance Tips for Long-Lasting Outdoor Lighting
To extend the life of your outdoor lighting, follow these maintenance tips:
- Regular Cleaning
- Wipe down light fixtures with a soft cloth and mild soap to prevent buildup.
- Remove debris and insects that can block light output.
- Check for Water Damage & Wear
- Inspect fixtures for corrosion, rust, or moisture inside the casing.
- Replace gaskets or seals if you notice condensation.
- Protect Against Harsh Weather
- Apply weatherproof sealant around wire connections.
- Use marine-grade coatings in salty or humid environments.
- Upgrade to LED for Longevity
- LED bulbs last longer and are more energy-efficient than traditional bulbs.
- Check for dimmable or smart-controlled LED options for better functionality.
Final Thoughts: Which Outdoor Lighting Should You Choose?
When choosing between waterproof and weatherproof lighting, think about how exposed your lights will be to rain, humidity, and potential submersion. If you’re lighting up a patio, weatherproof lights will do the job. But if your lights are near pools, fountains, or coastal areas, waterproof fixtures are a must.
