NVLAP EELPpartial range of approval：

At the same time, BACL was also accredited by IAS as an ANSI/IES LM-79:2019 testing laboratory, and became the testing institution with the testing method recognized by both IAS （Lab Code: TL-460） and NVLAP(Lab Code: 200707-0) . A number of latest lighting product standards methods had been successfully expanded and listed, once again enhancing the competitiveness and influence of BACL laboratory in the field of lighting testing.

Briefly introduction of ANSI/IES LM-79:2019’s testing method:

IESNA firstly published IES LM-79-08 in 2007, 12 years later,ANSI and IESNA jointly released the updated version of IES LM-79 standard:ANSI/IES LM-79:2019 Photoelectric test method for solid-state lighting products. From thisverision,standard IES LM-79 was upgraded to America standard ANSI/IES LM-79. IESNA updated the standards based on information gathered from the Laboratory Accreditation & Independent Research Competency Verification Test (PT test). This method is based on absolute photometry and meets the requirements of optical and electrical measurements of solid-state lighting products. This method has undergone significant changes in the structure of this standard compared to the previous version.At the same time, with the maturity of LED technology and the familiarity of LED technology parameters, this update removes some basic language descriptions.

Types of authentication affected byANSI/IES LM-79:2019:

IES LM-79-19 as a basical and important testing standard in SSL lighting,afterit’s first publishment in 2007, It has a very significant impact on the whole SSL lighting industry, The certification of Energy Efficiency in various countries(such as America Energystar,DLC,CEC,DOE,FTClabel,CEE,LDL; Australia's VEET,IPART etc；Brazil ordinance No. 20,Inmetro 389; Dutch energy investment subsidy: SME Lighting Support Scheme; British Columbia energy efficiency standards; Mexico NOM-031-ENER-2012,MexicoNOM-030-ENER-2016etc )takes it as the test standard.

Summary of major changes of ANSI/IES LM-79:2019：

Update requirements for measuring environment temperature, wind speed, and humidity, Increasethe power frequency error and power output response time requirements, Add four-wire method of test connection mode and parameter requirements such as line resistance and inductance. Update methods to determine stability, Integral sphere size selection method, measurement uncertainty requirements, The requirements of tolerance interval and acceptance interval are added.

In the future,BACL will provide one-stop solution for professional, efficient and accurate testing and certification as always and be ommittedto helpinglighting manufacturers to improve the efficiency ofreserch,launch more reliable quality, advanced technology of new products,quickly enter the international market Welcome to choose BACL as your reliable testing lab, We will create more value for you!
