When selecting LED lights for various applications, understanding their durability and protection levels is crucial. Two essential rating systems—IP (Ingress Protection) and IK (Impact Protection)—help users determine the suitability of LED lights for specific environments. This guide explores these ratings, explaining their significance and how to choose the right LED lighting for your needs.
What are IP Ratings
IP ratings, established by the International Electrotechnical Commission (IEC), define the degree of protection provided by enclosures against dust and water. IP codes in the UK are assigned according to British Standard BS EN 60529:1992. The rating consists of two digits:
First Digit (0-6): Protection against solid objects (e.g., dust, debris).
Second Digit (0-9): Protection against liquids (e.g., water, moisture)
Common IP Ratings for LED Lights
IP Rating
Protection Level
Suitable Applications
IP20
Basic protection against solid objects larger than 12.5mm but no water resistance
Indoor use
IP44
Protection against solid objects larger than 1mm and splashing water from any direction
Damp indoor environments
IP65
Fully dust-tight and resistant to low-pressure water jets
Outdoor use and wet areas
IP67
Fully dust-tight and can withstand immersion in water up to 1 meter for 30 minutes
Landscape and underwater lighting
IP68
Fully dust-tight and capable of continuous submersion in water
Extreme conditions like underwater lighting
What are IK Ratings
IK ratings measure the resistance of enclosures to mechanical impact. IK ratings are defined in international standards BS EN 62262 and IEC 600608-2-75.
IK Rating
Protection Level
Suitable Applications
IK06
Protection against 1 joule of impact (equivalent to a 500g object dropped from 20cm)
Standard indoor applications
IK08
Protection against 5 joules of impact (equivalent to a 1.7kg object dropped from 30cm)
Public spaces and outdoor lighting
IK10
Protection against 20 joules of impact (equivalent to a 5kg object dropped from 40cm)
Vandal-prone areas and industrial settings
Choosing the Right IP and IK Rating for Your LED Lights
When selecting LED lighting, consider the environmental conditions and potential physical impacts:
Indoor Use: IP20 is sufficient for dry areas, while IP44 is better for kitchens and bathrooms.
Outdoor Use: IP65 or higher is recommended to withstand rain and dust.
Industrial and Public Spaces: IK08 or IK10 ensures durability against accidental or intentional impacts.
Submersible Applications: IP67 or IP68 is required for underwater or extreme wet conditions.
Conclusion
Understanding IP and IK ratings helps in selecting durable LED lighting solutions that meet environmental and impact resistance needs. By choosing the appropriate rating, users can enhance the longevity, safety, and performance of their lighting systems in various applications.
