When selecting outdoor, high-powered LED floodlights and drivers, understanding IP ratings is important. These ratings ensure your equipment is equipped to handle the specific environmental conditions it will face.
In this article, we’ll break down the key differences between IP66 and IP67 ratings, helping you make an informed decision.
What Does an IP Rating Mean?
Ingress Protection (IP) ratings measure how well a product is shielded from solids and liquids. The rating comprises two numbers:
- First Digit: Protection against solid objects (e.g., dust).
- Second Digit: Protection against liquids (e.g., water).
For example, an IP66 rating offers a specific level of defence against solids and liquids, whereas an IP67 rating provides enhanced protection, especially against water.
What’s the Difference Between IP66 and IP67
- IP66 Rating
An IP66-rated luminaire is built to resist high-pressure water jets from any direction. This protection is tested using a 0.50-inch nozzle delivering high-pressure water for at least three minutes from a distance of three yards. This makes IP66-rated floodlights ideal for outdoor settings where heavy rainfall or powerful water sprays are common.
- IP67 Rating
IP67-rated enclosures go a step further by offering protection against water immersion. They are tested to withstand submersion in up to 1 metre of water for 30 minutes. This higher level of protection is especially beneficial in environments prone to water pooling or flooding.
Key Considerations When Choosing Between IP66 and IP67
When deciding on the most suitable IP rating, consider the specific environmental challenges your lighting will face:
- IP66 Floodlights: Ideal for areas exposed to rain, splashes, or high-pressure water jets, such as sports grounds or airport aprons.
- IP67 Floodlights: Perfect for environments where submersion in water is a possibility, like industrial sites with potential flooding or certain marine applications.
Which IP Rating Do You Need?
In summary, the primary difference between IP66 and IP67 is the level of water protection:
- IP66: Resists high-pressure water jets.
- IP67: Offers additional protection for temporary submersion.
Understanding these distinctions is key to choosing the right floodlight or driver for your application. Whether you’re designing lighting for a sports facility, airport apron, or port, selecting the correct IP rating ensures optimal performance and longevity for your fixtures.
