Intertek Lighting Testing

Lighting testing and certification is the process of independently evaluating lighting products to verify they meet applicable safety, performance, and regulatory requirements. Testing may include electrical safety, photometric performance, environmental durability, and reliability assessments. Certification confirms that products comply with recognized standards and are suitable for market access.

Lighting testing is required to demonstrate compliance with national and international standards, regulatory requirements, and market expectations. Independent testing helps ensure products are safe, perform as intended, and can be legally sold in target markets. Certification also provides confidence to regulators, retailers, and end users.

Intertek tests and certifies a wide range of lighting products, including lamps, luminaires, lighting components, controls, drivers, and connected lighting systems. Our services support general illumination as well as advanced and application-specific lighting technologies such as horticultural lighting, germicidal, UV systems, and emerging light sources.

Intertek provides lighting testing and certification to applicable UL, CSA, IEC, and other global standards, depending on product type and target market. Our experts help manufacturers identify the correct standards and testing pathways for North America and international markets.

The ETL Mark is a globally recognized proof of product compliance indicating that a lighting product has been independently tested and certified by Intertek to applicable safety standards. It is accepted by Authorities Having Jurisdiction (AHJs) and retailers across North America and supports regulatory compliance and market access.

Yes. The ETL Mark demonstrates compliance with the same applicable safety standards as other Nationally Recognized Testing Laboratory (NRTL) marks, such as UL or CSA. Acceptance is based on compliance with the standard—not the mark itself.

Lighting performance testing evaluates how a lighting product performs under defined conditions. This may include testing for light output, efficacy, color quality, flicker, lifetime, and durability. Performance testing supports product development, claim substantiation, energy programs, and customer confidence.

Performance testing helps manufacturers validate product claims, differentiate products in the market, and demonstrate compliance with program or customer requirements. It also supports product optimization and long-term reliability as lighting technologies continue to evolve.

Yes. Intertek offers integrated lighting safety and performance testing, allowing manufacturers to work with a single trusted partner across the product lifecycle. This streamlined approach helps reduce complexity, manage risk, and accelerate time to market.

Intertek’s lighting testing heritage dates back to 1896, when Electrical Testing Laboratories evaluated the performance of the first electric lightbulbs. Since then, Intertek has continuously supported the lighting industry as technologies evolved—from early electric lighting to today’s advanced and connected systems.

Intertek adapts its testing capabilities to support new materials, designs, applications, and technologies as they enter the market. Our experts work closely with manufacturers to address evolving performance expectations, regulatory requirements, and real-world use cases.

Yes. Intertek provides lighting testing and certification services to support global market access, helping manufacturers navigate regional requirements and standards efficiently. Our international network allows products to be tested and certified for multiple markets through a coordinated approach.

Manufacturers benefit from engaging a testing partner early in product development. Early involvement helps identify compliance requirements, reduce redesigns, and streamline testing and certification as products move toward commercialization.

Manufacturers choose Intertek for lighting testing due to our independent expertise, global recognition, integrated services, deep industry experience, and our speed to market DNA. With a heritage rooted in the earliest days of electric lighting, Intertek continues to support today’s technologies—and the innovations still ahead.
