LED Testing and Certification Solutions

LED testing is the process of evaluating and assessing the performance, quality, and safety of LED (Light Emitting Diode) lighting products. It involves conducting various tests and measurements to ensure that the LED lights meet industry standards and regulatory requirements. LED testing typically includes:

• Luminous efficacy: Measuring the amount of visible light output in relation to the electrical power input, usually expressed in lumens per watt (lm/W).
• Color characteristics: Assessing the color temperature (measured in Kelvin) and color rendering index (CRI) to ensure the LED light produces the desired color and accurately renders colors of objects.
• Lifetime and reliability: Evaluating the lifespan of the LED lighting product by conducting accelerated aging tests to estimate its durability and longevity.
• Electrical safety: Verifying compliance with electrical safety standards to ensure that the LED lighting product does not pose any electrical hazards, such as insulation resistance, dielectric strength, and electrical leakage.
• Thermal management: Assessing the ability of the LED light to dissipate heat effectively, preventing overheating and maintaining optimal performance.
• Environmental and energy efficiency: Testing for energy consumption, efficiency, and compliance with environmental regulations, such as Energy Star^® or EPEAT certifications.

Leveraging LED sources with demonstrated compliance to applicable lumen maintenance and/or color maintenance performance requirements enables a more efficient LED testing and certification process for lamps and luminaires.

LEDs tested by a third party to applicable standards, such as LM-80 with 6,000 minimum testing hours required, will minimize delays in meeting energy efficiency requirements such as Energy-related Products (ErP) Directive, ENERGY STAR^®, or DesignLights Consortium™ (DLC).

While LED lamp and luminaire development is typically measured in months, utilizing suitably-rated components can expedite energy efficiency program testing or certification to a matter of weeks.

UL 8750 - LED Equipment Safety Standard

UL 8750 is the recognized North American safety standard for LED equipment used in lighting products, focusing on the internal components such as LED modules, arrays, drivers, and associated electronics rather than complete fixtures (which are covered by UL 1598). It defines requirements for electrical insulation, grounding, overcurrent protection, thermal management, fire resistance, and mechanical integrity to ensure safe and reliable operation. Testing LED components and drivers to UL 8750 helps manufacturers demonstrate regulatory compliance, enhance product reliability, streamline market access, and build customer trust—especially when combined with complete luminaire certification. Intertek offers comprehensive UL 8750 services, including safety testing, ETL certification, tailored test planning, and related performance evaluations, supported by its global accredited laboratory network.
