SGS Consumer Testing Services, a leading global provider of verification, testing and certification services, today announced an expansion of its solid state luminaire testing services in North America to encompass LM-79 photometric measurements through a partnership with Gamma Scientific, a manufacturer of precision light measurement equipment and LED testing solutions. Complete lighting service solutions – including safety, EMC, performance, ENERGY STAR® and photometric evaluations – will now be offered as a single consolidated source for faster service.

Safety, EMC and performance testing will be performed by SGS’ dedicated E&E lab in Atlanta, with optional ENERGY STAR® energy efficiency testing under the same roof. Photometric testing will be handled at Gamma Scientific’s NVLAP-accredited laboratory (lab code 200823-0) in San Diego, which has LM-79 accreditation for Solid State Lighting Luminaires – Total Flux Measurements (Luminous Efficacy) and Solid State Lighting Luminaires –Luminous Intensity Measurements.

Benefits for luminaire companies include the ability to source all services from a single provider and deal with one account manager for faster communication and better accountability, enabling the creation of custom testing schedules to meet market demands.

Specific advantages of working with Gamma Scientific for photometry testing include:

  • Experience in performing photometry testing on LED and LED retrofit lighting products ranging from LED light bulbs to high bay fixtures and street lights.
  • The availability of state-of-the-art equipment developed and manufactured by Gamma Scientific to provide total LED test solutions.
  • The ability to test luminaires up to 30” x 30” for Luminous Intensity Distribution, with a new goniometer that allows testing of lamp tubes as long as 4 feet.

For global manufacturers, SGS also offers photometry testing at its own labs in Finland and Taiwan and provides other lighting testing services at offices around the world with CB Scheme Certification as well as local country approvals including CCC Certification for China, BSMI Certification for Taiwan, ENEC for the European Union and others. In the U.S., SGS has been an OSHA Nationally Recognized Testing Laboratory (NRTL) since 1998. 

“The rapid growth of solid state lighting has created a need to streamline the testing process to help luminaire manufacturers save time, reduce administrative overhead, and bring their products to market faster,” said Ozgur Ozturk, Manager of Operations, SGS Atlanta. “Our partnership with Gamma Scientific accomplishes those objectives by allowing manufacturers to use SGS as a central point of contact for all testing services.”   

“We have been developing instruments to perform LED testing and measurement since 1979 , including high-performance spectroradiometers, spectrometers, integrating spheres and turnkey LED test systems. As a result, we now have testing solutions for any LED application as well as an in-house NVLAP-accredited laboratory using our own equipment,” said Richard Austin, President at Gamma Scientific. “SGS customers can now take advantage of these capabilities to ensure fast, accurate photometric testing in conjunction with other SGS services.”
