LED Testing and Certifications

There is a lot of regulation that governs how lights should behave, what safety regulations they need to follow, and what their true light output specifications are. Through the use of many tests and certifications, customers can rest easy knowing their products have been tested and approved for safety and effectiveness. The important tests and certifications for LED lights are described below. 


Important tests- 

  • LM79 - Conducted by the Illuminating Engineering Society of North America (IESNA), this test is an approved method for measuring an LED luminaire or integral lamp as a whole system using specified equipment to ensure consistent results. This test provides the total luminous flux, luminous intensity distribution, electrical power characteristics, lumen output efficacy, and color characteristics like CRI and CCT. 
  • LM80- Also conducted by IESNA, this test is the approved standard for measuring lumen maintenance of LED sources. This test can apply to any piece of the LED system rather than the entire system itself, and is used by the Energy Star program to determine the rated lifespans of LED lights. 

Certifications available for LED lighting-

  • CE- The European Commission (CE) mark is used to certify an industrial product for sale in the European Union. The CE mark certifies that products have passed EU safety, health, and environmental tests. 
  • DLC- The Design Lights Consortium is a non-profit organization dedicated to promoting solid-state lighting and accelerating adoption of new lighting technologies for commercial environments. If a product is DLC certified, it has passed all of their internal testing related to product reliability and effectiveness. A huge perk to DLC certification is that it gives the consumer the ability to find accurate test results for the products on the DLC database, meaning they will know exactly what they are getting out of their lights. 
  • ETL Listed- The Edison Test Laboratories (ETL) mark is proof of compliance to North American safety standards. All 50 states of the USA and Canada accept the ETL listing as proof of product safety.
  • Energy Star- Energy Star certification is used to certify that a product produces 75% less energy than a comparable incandescent, lasts 15 times longer than an incandescent, has brightness equal or greater than existing technologies, will maintain its light output over greater time periods, and has excellent color quality. Energy Star certification is hard to find on LED products for cheap, and also allows for Instant Rebates from Xcel Energy (applies to Colorado only). 
  • UL Listed- If a product is UL Listed, it means that product has been tested by the Underwriters Laboratories (UL) and has passed their process for safety. UL listing opens the door to many utility rebate opportunities and proves that a product has been rigorously tested by a trusted organization.
