IP Ratings Explained: Understanding Waterproof LED Lights

LED lights have transformed modern lighting design with their efficiency, durability, and versatility. From sleek indoor installations to rugged outdoor applications, they’re found everywhere. But when your project involves moisture, rain, dust, or full submersion, selecting the right waterproof LED light is critical.

This is where IP ratings come into play—a standardized system that tells you how well a product can resist dust and water.


💡 What Is an IP Rating?

IP stands for Ingress Protection. It’s a globally recognized standard (defined by IEC 60529) that classifies the level of protection an electrical enclosure offers against solids and liquids.

Each IP rating has two digits:

  • The first digit (0–6) represents protection against solids (like dust and dirt)
  • The second digit (0–9) represents protection against liquids (like splashing water or immersion)

The higher the number, the greater the protection.


🔢 IP Rating Breakdown

Let’s look at what each digit means in practical terms:

First Digit – Protection Against Solids

DigitProtection Level
0No protection
1Protection from large objects (>50mm)
2Protection from medium objects (>12.5mm)
3Protection from small objects (>2.5mm)
4Protection from most wires or screws (>1mm)
5Partial dust protection
6Dust-tight (complete protection from dust)

Second Digit – Protection Against Liquids

DigitProtection Level
0No protection
1Protection from vertically dripping water
2Protection from water dripping at a 15° angle
3Protection from water spray at up to 60°
4Protection from splashes from all directions
5Protection from low-pressure water jets
6Protection from strong water jets
7Protection from temporary immersion (up to 1m)
8Protection from continuous immersion (beyond 1m)
9Protection from high-pressure, high-temperature jets (usually industrial use)

✅ Common IP Ratings for LED Lights

Here are some common IP ratings used in LED strip lights and fixtures, and where you’d typically use them:


🔸 IP20 – Indoor Only

  • Protection: Limited dust protection, no water resistance
  • Use for: Dry, indoor spaces like living rooms, bedrooms, ceilings

✅ Best for: General residential use where water isn’t a concern.


🔸 IP64 – Light Splash Resistance

  • Protection: Dust tight; protected from water spray at specific angles
  • Use for: Covered patios, soffits, damp indoor areas (not exposed to full rain)

✅ Best for: Semi-exposed outdoor areas or humid rooms.


🔸 IP65 – Water-Resistant Outdoor Use

  • Protection: Dust-tight; protected from water jets from any direction
  • Use for: Outdoor walls, under-eaves, garden lighting, bathroom zones

✅ Best for: Rain-exposed but not submerged environments.


🔸 IP68 – Fully Waterproof for Submersion

  • Protection: Completely dust-tight; can be fully submerged in water (typically over 1m)
  • Use for: Pools, fountains, aquariums, underwater architecture

✅ Best for: Continuous underwater use or severe wet conditions.


🛠️ Choosing the Right IP Rating for Your LED Project

When selecting LED lights for your project, ask yourself:

  • Will it be used indoors or outdoors?
  • Will it be exposed to splashes or rain?
  • Is it going to be submerged in water?
  • Will it be installed in a dusty or dirty area?

Matching the IP rating to your environment ensures the long-term performance and safety of your lighting system.


📌 Final Thoughts

IP ratings are more than just technical specs—they’re essential to choosing the right LED light for your space. Whether you’re installing LEDs in a dry living room or submerging them in a pond, there’s a product with the right protection for your needs.

🛒 Pro Tip: Always check the product label or spec sheet for its IP rating before buying.
