Understanding IP Ratings and Certifications for UFO High Bay Lights

Understanding IP Ratings and Certifications for UFO High Bay Lights

When buying UFO high bay lights, it's not enough to just consider wattage and lumens. To ensure your investment is safe, reliable, and durable in a commercial or industrial environment, you need to understand key technical specifications like IP ratings and various certifications. These ratings tell you how well a fixture is protected from the elements and if it meets industry standards.¹

What Is an IP Rating?

An IP (Ingress Protection) rating is a globally recognized standard that measures a fixture's resistance to dust and moisture.² It's crucial for determining if a light can withstand the conditions of a specific environment.³ The IP code consists of two digits.⁴ The first digit represents protection against solids (dust, debris, etc.), and the second represents protection against liquids (water).⁵

• First Digit (Solids):

  • 0: No protection.⁶

     

  • 6: Fully protected against dust ingress ("dust-tight").⁷ This is the most common rating for high-quality UFO high bays and is essential for dusty environments like warehouses or manufacturing plants.

     

• Second Digit (Liquids):

  • 0: No protection.⁸

     

  • 5: Protected against low-pressure water jets from any direction.⁹

     

  • 6: Protected against high-pressure water jets.¹⁰

     

  • 7: Protected against temporary immersion in water.¹¹

     

The most common and recommended rating for UFO high bays is IP65.¹² This means the fixture is completely sealed against dust and can withstand water jets, making it suitable for a wide range of applications, including those where occasional cleaning with a hose is required.¹³

Why Are Certifications So Important?

Certifications from third-party organizations are a stamp of quality, safety, and performance.¹⁴ They are a buyer's assurance that a product has been independently tested and meets rigorous standards.¹⁵ In the US, two certifications are particularly critical for UFO high bay lights.

1. DLC Certification

DLC (DesignLights Consortium) is a non-profit organization that promotes high-quality, energy-efficient lighting.¹⁶ A fixture that is DLC certified has been tested to meet strict performance and efficiency standards.¹⁷

• Why it matters: DLC-certified products are proven to be energy-efficient and long-lasting.¹⁸ Critically, in the United States, most utility companies and government programs require DLC certification for a fixture to be eligible for energy rebates. Choosing a DLC-certified product can significantly reduce your upfront costs and shorten the return on investment.

   

2. UL Certification

UL (Underwriters Laboratories) is a globally recognized safety science company. A UL-listed product has been tested to ensure it meets safety standards and does not pose a fire or electrical hazard.

• Why it matters: UL listing is an absolute necessity. A product without this certification could be dangerous and non-compliant with local building codes. It's a simple, non-negotiable step to ensure the safety of your facility and employees.

Putting It All Together: A Buyer's Checklist

Before purchasing, use this checklist to ensure the UFO high bay you've chosen is right for your application.

By prioritizing fixtures with the right IP rating and the necessary certifications, you can confidently invest in UFO high bay lights that are not only high-performing and energy-efficient but also safe and durable for years to come.
