How the IP Rating System Works
The IP rating system uses two digits to classify an LED light’s ability to resist solids and liquids. The first digit (ranging from 0 to 6) measures protection against solid objects like dust, while the second digit (ranging from 0 to 9) indicates resistance to water.
First Number: Protection Against Solids
The first digit shows how effectively the LED fixture is shielded from dust and other particles. A rating of 0 means no protection, while a 6 ensures the fixture is completely dust-tight, making it excellent for outdoor areas or bathrooms. Ratings of 5 or 6 are ideal for environments with airborne particles.
Second Number: Protection Against Liquids
The second digit evaluates water resistance. A 0 means no protection from water, while higher numbers indicate increased resistance. Here’s a quick breakdown:
- IP44: Splash-proof, suitable for many bathroom settings.
- IP65: Withstands water jets, making it a go-to for outdoor spaces exposed to rain.
- IP67: Handles temporary submersion (up to 1 meter or about 3.3 feet for 30 minutes), perfect for areas like poolsides.
- IP68: Designed for continuous immersion (up to 3 meters or around 9.8 feet), ideal for underwater applications like fountains or marine environments.
- IP69: Offers extra protection against high-pressure, high-temperature water jets, though it’s rare in residential lighting.
This system helps users choose the right fixture for their specific needs, as summarized in the table below.
Common IP Ratings for LED Lights
| IP Rating | Solids Protection | Liquids Protection | Typical Use Cases |
|---|---|---|---|
| IP20 | Protects against large objects (e.g., fingers) | None | Indoor, dry areas |
| IP44 | Blocks particles as small as 1 mm | Splash-proof | Bathrooms, covered outdoor areas |
| IP65 | Dust-tight | Resistant to water jets | Outdoor spaces, rain, garden lighting |
| IP67 | Dust-tight | Temporary immersion (up to 1 m/3.3 ft for 30 minutes) | Poolsides, areas prone to occasional flooding |
| IP68 | Dust-tight | Continuous immersion (typically up to 3 m/9.8 ft) | Underwater applications, fountains, marine settings |
Both digits are equally important. For example, a fixture with strong water resistance but poor dust protection may still fail in dusty environments where both factors matter.
Selecting the Right IP Rating for Wet Areas
Choosing the correct IP rating for bathroom fixtures depends entirely on the level of water exposure they’ll face. Each area in a bathroom has unique requirements, so it’s important to match the rating to the specific conditions of that space.
IP Ratings for Different Bathroom Areas
For shower enclosures, an IP65 rating or higher is recommended to handle direct water exposure. In spaces like shower niches or areas near bathtubs where temporary submersion might occur, IP67 is the best choice. This rating ensures protection against immersion in water up to 3.3 feet (about 1 meter) for up to 30 minutes – ideal for scenarios like overflowing tubs or pooled water during cleaning tasks.
Above vanities and sinks, IP44-rated fixtures are sufficient. For toe kick or under-cabinet lighting, either IP44 or IP54 ratings work well, offering both water and dust resistance. Products like Thunder Bunny’s Floating or Toe Kick Vanity LED Light Kit are designed to meet these needs.
Ceiling fixtures require extra attention, especially when installed near water sources. General ceiling lights outside splash zones can use an IP44 rating, but fixtures directly above bathtubs or showers should have an IP65 rating to handle exposure to steam and occasional splashes.
What to Consider When Choosing an IP Rating
When selecting an IP rating, the primary factor is how much water exposure the fixture will face. Areas with frequent splashing or potential submersion demand higher-rated fixtures, while spaces with occasional moisture can use lower ratings.
The installation location also matters. Fixtures near the floor are more likely to encounter water from cleaning or flooding, so they need higher protection. Wall-mounted lights, on the other hand, mostly deal with splashes. For example, Thunder Bunny’s Shower Niche LED Lighting Kit is specifically designed for high-moisture shower environments.
Durability is another consideration. Fixtures exposed to cleaning chemicals, physical impacts, or temperature changes can benefit from higher IP ratings, though these may come with added costs and bulkier designs.
Maintenance and ease of replacement are also important. While fixtures with higher IP ratings often last longer in wet areas, they might require more complex installations or specialized mounting hardware. Balancing long-term durability with ease of access is key.
Although local building codes in the United States don’t enforce specific IP ratings, the National Electrical Code requires fixtures in wet locations to be appropriately rated. Many inspectors suggest using IP44 or higher for damp areas and IP65 or higher for wet zones to ensure safety and compliance.
Finally, weigh the cost against the level of protection needed. Higher IP ratings provide better durability and safety, but they’re typically more expensive and may have design limitations. For areas with minimal water exposure, lower ratings might suffice, but in wetter zones, investing in higher-rated fixtures can save money in the long run by reducing maintenance and improving safety.

| IP67 | Dust-tight and can handle temporary submersion (up to 3.3 feet for 30 minutes) | Works well in shower niches, pool areas, and flood-prone zones | Not intended for continuous immersion; comes with higher upfront costs | More expensive compared to lower-rated options |
As you move from IP44 to IP67, the level of protection increases significantly, but so do the costs and complexity of installation. The table highlights key differences, but let’s dive deeper into the practical trade-offs.
Higher vs. Lower IP Rating Trade-offs
Lower IP ratings, like IP44, are more budget-friendly and use simpler sealing techniques. However, these fixtures tend to have a shorter lifespan in wet environments, typically lasting 3–5 years. On the other hand, higher ratings, such as IP67, are more durable – often exceeding 15 years – but come with added costs and installation challenges.
For many residential applications, IP65 strikes a good balance. It provides reliable protection in outdoor settings, with an average lifespan of 7–10 years, while remaining relatively affordable. However, it doesn’t offer protection against submersion, which may be necessary in specific scenarios.
Fixtures with higher ratings often require more frequent inspections for potential moisture damage, while lower-rated options demand careful installation but less ongoing maintenance. Additionally, warranties can vary based on the IP rating. Manufacturers may void warranties if a fixture is used in conditions beyond its rated protection, so it’s essential to match the rating to the intended environment.
In high-moisture areas, higher-rated fixtures are well worth the investment, while lower-rated options can perform adequately in less demanding settings. Choosing the correct IP rating ensures both durability and value for your application.
