The IP protection rating determines how resistant a lighting unit is to dust and water, and choosing the right rating varies by location: dry indoor areas are fine with low ratings, while wet and outdoor areas need higher ratings to ensure safety and a long life.
Quick answer: Dry indoor = IP20; bathroom/kitchen near water = IP44–IP65; outdoor exposed to rain = IP65; submerged in water (pool/fountain) = IP67–IP68.
What does IP mean, briefly?
The IP code is followed by two digits: the first for dust resistance (0–6), the second for water resistance (0–8). The higher the numbers, the greater the protection.
Indoor lighting: which rating do you need?
- Bedrooms, living rooms, hallways (dry): IP20 is enough.
- Kitchen (near the sink and steam): IP44 or higher.
- Bathroom (away from splashes): IP44, and near the shower/tub IP65.
Outdoor lighting: which rating do you need?
- Covered balconies: IP54 or higher.
- Facades and gardens (exposed to rain): IP65.
- In-ground and recessed paths: IP67.
- Pools and fountains (submerged): IP68.
Why does the rating differ between indoor and outdoor?
- Outdoors is exposed to rain, dust, and weather changes.
- Wet areas need water sealing to prevent shorts and corrosion.
- A higher rating extends life and keeps things safe.
Quick guide by location
- Bedroom/living room: IP20.
- Kitchen: IP44+.
- Bathroom (splash zone): IP65.
- Garden/facade: IP65.
- Outdoor flooring: IP67.
- Pool: IP68.
Important tips
- Do not use an indoor unit (IP20) in an outdoor or wet spot.
- Mind the quality of the seals, not just the number.
- Make sure connectors and cables match the installation environment.
Frequently asked questions
What is the minimum rating for a bathroom?
IP44 away from water, and IP65 near the shower.
Is IP65 enough for a garden?
Yes for rain-exposed areas; for submerged spots choose IP67/68.
Is a higher number always necessary?
No; choose by the location environment to balance cost and protection.
Conclusion
Choosing the IP rating for lighting depends on the location: low for dry indoors, high for wet, outdoor, and submerged. Matching the rating to the environment ensures safe lighting that lasts.
