Certifications and Standards for LED High Bay Lights


LED high bay lights are a critical component of industrial settings, providing efficient and powerful illumination in large spaces such as warehouses, manufacturing facilities, and sports arenas. Given their significant energy and maintenance cost savings, these lighting solutions have become increasingly popular. However, with the plethora of options available, it can be challenging to determine the best products for your specific needs.

This is where certifications and industry standards come in. Recognized institutions like DLC (DesignLights Consortium), UL (Underwriters Laboratories), and IP (Ingress Protection) ratings ensure that LED high bay lights meet strict guidelines in terms of quality, safety, and efficiency. This blog will help you navigate these certifications and standards to make an informed decision when choosing LED high bay lights for your industrial applications.

DLC Certification: Ensuring Energy Efficiency and Performance

The DesignLights Consortium (DLC) is a non-profit organization that advocates for energy-efficient lighting. The DLC certification establishes performance and efficiency standards for commercial and industrial LED lighting products, with the primary goal of reducing energy consumption.

When selecting LED high bay lights, opting for a DLC-certified product ensures that the lighting solution meets specific performance criteria, such as:

  1. Luminous efficacy: A measure of how efficiently the fixture converts electrical energy into visible light.
  2. Lumen maintenance: The ability of the light source to maintain its brightness over time.
  3. Color rendering index (CRI): How accurately the light source represents the colors of objects it illuminates.

UL Certification: Prioritizing Safety and Quality

Underwriters Laboratories (UL) is a global safety certification organization that sets stringent standards for electrical devices, including LED high bay lights. UL certification indicates that a product has been rigorously tested for potential hazards and meets established safety requirements.

By choosing UL-certified LED high bay lights, you can be confident in the safety and reliability of the product, minimizing risks such as electrical fires, electrocution, or other hazards. This certification also ensures that the product complies with regional safety regulations and building codes, which is vital for industrial applications.

IP Ratings: Assessing Ingress Protection

In industrial environments, LED high bay lights are often exposed to various environmental factors such as dust, water, and other contaminants. IP ratings serve as a standardized measurement to determine the level of protection a lighting fixture offers against these elements.

The IP rating system consists of two digits:

  1. The first digit (0-6) indicates the level of protection against solid particles (such as dust).
  2. The second digit (0-9) represents the level of protection against water ingress.

For example, an IP65-rated LED high bay light is dust-tight and can withstand low-pressure water jets from any direction. Depending on the specific needs of your industrial application, selecting a product with the appropriate IP rating is essential for ensuring the longevity and performance of your LED high bay lights.

In addition to DLC, UL, and IP ratings, there are several other certifications and standards that can be relevant when choosing LED high bay lights. Some of these include:

  1. ETL (Intertek Testing Services): ETL is a safety certification provided by Intertek, a global testing, inspection, and certification company. Similar to UL, ETL certification verifies that a product meets North American safety standards, ensuring its reliability and safety. Although UL is more widely recognized, ETL is also a reliable indicator of product quality.
  2. CE (Conformité Européene): The CE mark is a certification that indicates a product complies with European Union (EU) safety, health, and environmental protection requirements. For LED high bay lights sold within the EU, the CE mark is mandatory and signifies that the product meets EU directives and regulations, such as the Low Voltage Directive and Electromagnetic Compatibility Directive.
  3. RoHS (Restriction of Hazardous Substances): RoHS is a European directive that restricts the use of specific hazardous substances in electrical and electronic equipment. RoHS-compliant LED high bay lights ensure that they are manufactured with a focus on environmental responsibility and sustainability, avoiding the use of harmful substances such as lead, mercury, and cadmium.
  4. Energy Star: Energy Star is a U.S. Environmental Protection Agency (EPA) program that promotes energy efficiency in products and buildings. LED high bay lights with the Energy Star label have been independently certified to meet strict performance requirements, delivering energy savings without compromising on quality or performance.
  5. LM-79 and LM-80: These are testing standards developed by the Illuminating Engineering Society (IES) to evaluate the performance of LED lighting products. LM-79 measures the luminous efficacy, color temperature, and color rendering index (CRI) of an LED product, while LM-80 tests the lumen depreciation over time. Compliance with these standards indicates that an LED high bay light has been thoroughly tested for performance and reliability.
  6. FCC (Federal Communications Commission): The FCC certification ensures that LED high bay lights meet electromagnetic interference (EMI) standards in the United States. This helps prevent interference with other electronic devices, ensuring smooth operation in industrial settings.

While the previously mentioned certifications are among the most common and important for LED high bay lights, there are a few more certifications to consider depending on your location and specific needs:

  1. TÜV (Technischer Überwachungsverein): TÜV is a German-based certification organization that evaluates the safety and quality of various products, including LED high bay lights. Similar to UL and ETL, TÜV certification ensures that the lighting solution adheres to strict safety and performance standards, primarily for the European market.
  2. SAA (Standards Australia and Standards New Zealand): SAA is a joint certification for products sold in Australia and New Zealand. LED high bay lights with SAA certification have been tested and verified to meet the safety and performance standards required by these countries.
  3. PSE (Product Safety Electrical Appliance & Material): The PSE certification is a Japanese safety standard for electrical appliances and materials, including LED high bay lights. This certification ensures that products sold in Japan comply with local safety regulations and quality requirements.
  4. CCC (China Compulsory Certificate): The CCC certification is a mandatory safety and quality certification for various products, including LED high bay lights, sold in China. This certification guarantees that the product meets the Chinese government’s safety and performance standards.
  5. C-tick and RCM (Regulatory Compliance Mark): These are Australian and New Zealand certifications for electromagnetic compatibility (EMC), ensuring that LED high bay lights do not cause interference with other electronic devices. The RCM mark has replaced the C-tick mark, indicating that the product complies with both EMC and electrical safety requirements.
  6. IK Rating: The IK rating is an international standard that measures the degree of protection provided by electrical enclosures against external mechanical impacts. This rating is particularly relevant for LED high bay lights installed in environments where they may be exposed to potential impacts, such as in manufacturing facilities or warehouses.

While this list covers several additional certifications, it’s crucial to prioritize the certifications most relevant to your location and application. By doing so, you can ensure that your chosen LED high bay lights are safe, reliable, and compliant with local regulations and industry standards.


Navigating certifications and industry standards when choosing LED high bay lights can be overwhelming. However, understanding the significance of DLC, UL, and IP ratings will help you select a high-quality, safe, and efficient lighting solution for your industrial application. By prioritizing these certifications and standards, you can optimize energy savings, reduce maintenance costs, and improve overall workplace safety.
