Choosing bathroom lighting is not just an aesthetic issue, but also a safety issue. In this article, we will discuss IP ratings and their importance when choosing bathroom lighting.
What does IP rating mean?
The IP rating (Ingress Protection) indicates how well an electrical device is protected from external factors, such as dust and moisture. The IP rating consists of two numbers:
- The first number (0-6) indicates protection against solid objects and dust.
- The second number (0-8) indicates protection against water and moisture.
For example, in the IP44 rating, the first 4 means protection against objects larger than 1 mm, and the second 4 means protection against splashing water.
IP ratings suitable for the bathroom
The bathroom is divided into different areas according to the risk of moisture:
Area 0: Shower or bathtub
- This is an area where water is constantly present.
- Required IP rating: at least IP67
- In this area, the luminaire must withstand immersion in water
Zone 1: Up to 225 cm above the shower or bathtub
- An area where splashing water is constantly present
- Required IP rating: at least IP65
- The luminaire must withstand water jets from all directions.
Area 2: 60 cm from area 1
- Area where splash water is possible
- Required IP rating: at least IP44
- The luminaire must withstand splashes from all directions
Area 3: Other bathroom space
- An area where humidity is generally lower
- Recommended IP rating: at least IP21
- The luminaire must withstand vertical dripping water
A more detailed explanation of IP ratings
First number (protection against solid objects):
- 0 : No protection
- 1 : Protection against objects larger than 50 mm
- 2 : Protection against objects larger than 12.5 mm
- 3 : Protection against objects larger than 2.5 mm
- 4 : Protection against objects larger than 1 mm
- 5 : Dust-proof (dust does not affect operation)
- 6 : Dustproof
Second number (protection against water):
- 0 : No protection
- 1 : Protection against vertically dripping water
- 2 : Protection against dripping water (at an angle of 15°)
- 3 : Rain protection (at 60° angle)
- 4 : Protection against splash water
- 5 : Protection against water jets
- 6 : Protection against powerful water jets
- 7 : Protection against short-term immersion
- 8 : Protection against continuous immersion
Tips for choosing bathroom lighting
1. Safety first
- Always check the IP rating of the luminaire before purchasing.
- Make sure the luminaire is suitable for the installation area
- Use a professional electrician for installation
2. Lighting design
- For general lighting, a ceiling light with an IP rating of at least IP44
- IP44 rated lamps for mirror lighting on the sides or above the mirror
- Indirect lighting for mood lighting, for example LED strip (IP65)
3. Selection of light sources
- LED lights are energy efficient and long-lasting
- A color temperature of 3000-4000K is usually pleasant in the bathroom.
- Dimmable lamps increase comfort
4. Lighting that suits the style
- Minimalist, chrome or steel-finished lamps are suitable for a modern bathroom.
- More classic lamps with glass or brass surfaces are suitable for a traditional style.
- Light, wood-finished or white lamps are suitable for Scandinavian style.
The most common mistakes in bathroom lighting
-
IP rating too low
- Safety risk and shorter lamp life
-
Insufficient lighting
- Good lighting is needed, especially in front of the mirror.
-
Only one light source
- Versatile lighting for different purposes is more practical
-
Wrong color temperature
- Too cold light can make a space feel uncomfortable
Summary
When choosing bathroom lighting, the IP rating is a paramount safety factor. Always make sure that the luminaire meets the requirements of the installation area. Properly selected lighting makes the bathroom both safe and comfortable.
Remember that electrical installations require a permit, so always use a professional electrician to install your lights. This will ensure that your bathroom lighting is both safe and compliant.
