The most important in lighting fixture certification is lumen maintenance value and LED supplier has to submit at least 6,000 hours validation data(LM-80 tests) of LED component(Package/Array/Module) according to IESNA LM-80 test method, and then, luminaire company would predict the lumen maintenance with referring to IESNA TM-21 methodology and LM-80 testing result, in order to deliver the life information of luminaire to consumers.

Instead of the traditional testing methodology(uses general temperature and humidity chamber with driving current source), DERKA iST adopts the dedicated equipment of LM-80 tests and can simulate the real environment of LED lamps/Luminaire. Therefore, clients could just deliver LED components to DEKRA iST, and we would offer the one-stop-shop validation services to fulfill the requirements of LM-80 test.

 About LED Luminaire Certification of U.S. Energy Star® 
In 2011, the ENERGY STAR rating of the US EPA, combined two specifications, Residential Light Fixtures (RLF) and Solid State Lighting (SSL), into the ENERGY STAR® Luminaries (Light Fixtures) – Version 1.1 and it executes from April 1st, 2012. The specification clearly describes the requirements of lighting fixtures and most LED suppliers already follow this standard to qualify their products. Furthermore, if luminaire company pursue the ENERGY STAR® certification, certification not only represents compliance with the requirements of the North American lighting market, but also represents that the performance of LED lighting has achieved an international standard, which in turn can substantially upgrade the product.
