What is an IP Rating?

An IP rating (Ingress Protection) indicates the degree of protection a light fixture has against solids and liquids. It's particularly important for lights used in bathrooms and outdoor areas where specific safety standards must be met. 

First Number (Solids Protection): This ranges from 0 to 6. The higher the number, the better the protection against solid objects, such as dust. 

Second Number (Water Protection): This ranges from 0 to 9. A higher number means better protection against water ingress. For example, an IP65 rating means the light is dust-tight and protected against water jets. 

In the US and Canada, the National Electrical Manufacturers Association (NEMA) ratings and environmental ratings are used. 

Here’s a rough equivalent: 

• IP20: Equivalent to NEMA 1. Basic protection against touch and condensation. 
• IP44: Equivalent to NEMA 3. Protection against light splashing water and small objects. 
• IP65: Equivalent to NEMA 4. Protection against water jets and dust. 
• IP67: Equivalent to NEMA 6. Protection against temporary immersion in water.

• Dry Locations: Suitable for areas not exposed to moisture, like living rooms and bedrooms. 
• Damp Locations: Suitable for areas with occasional condensation or moisture, such as bathrooms (outside shower areas) and covered porches. 
• Wet Locations: Suitable for areas directly exposed to water, like shower areas, outdoor locations, or areas subject to rain. 

Bathrooms: Generally, a minimum of IP44 is recommended for lights in zones exposed to moisture (damp locations).

Outdoor Areas: A minimum of IP65 is advised to ensure durability against weather conditions (wet locations).
