What Is LM 79 Testing lab and Need & Methods of LM Testing

LM-79 testing measures the performance of products that use solid-state lighting (SSL) technology, such as light-emitting diodes (LEDs). This testing provides a snapshot of performance under specified operating conditions at some point in a product's life, typically at the start of operation—these are known as initial measurements. It makes no mention of lifetime ratings, changes in performance over time (for example, lumen maintenance), or LED case temperature. The LM-79 method can be used on integrated LED products like luminaires and replacement lamps. It doesn't apply to LED packages, modules, or arrays (herein collectively referred to as LED light sources). LM-79 data allows for objective product comparisons and evaluation in relation to performance requirements. Although LM-79 does not specify a report format or minimum content, it does provide a lengthy list of "typical items reported." Electrical characteristics, lumen output, spatial distribution of light...

LED-based solid-state lighting (SSL) products offer many advantages over incandescent lamps, but they present unique challenges for performance measurements. LM-79 was developed by the Illuminating Engineering Society (IES) to standardize the photometric and electrical measurements of LED-based SSL products and is the benchmark test for lighting manufacturers and numerous qualification programs. KC India testing laboratory is ISO accredited by A2LA for LM-79 luminous flux (lumen) and color measurements. KC India is also a Design Lights Consortium (DLC) approved LM-79 testing laboratory for lamps and luminaires.

LM-79 Testing Laboratory KC India LM-79 is an approved method for testing electrical and photometric measurements of solid-state lighting products. LM-79 contains procedures for performing reproducible measurements of LEDs properties, including: total flux, electrical power, efficacy and chromaticity. LM 79 testing labs , Photometric Testing, Luminaire Testing Lab , LED Tests LM-79 India.  How LM-79 testing can help assess LED luminary quality and performance? We all believe in buying quality products. Discovery of LED is boon to our world. LED has replaced all the traditional lightning systems because of its quality, life and performance.  Manufacturers are switching from manufacturing traditional lightning to produce LED lighting. Many of the manufacturers are making unsubstantial claims regarding colour quality, luminous flux (lm), efficacy (lm/w) and general quality. This can Lead to LED degradation. To ensure quality, a series of test has to be performed on LED luminaries...

LM-79 Testing Laboratory in India KC India Ghaziabad (UP) is a accredited laboratory through NABL under photometry testing providing LM-79 Testing. It has a scope to test Solid state lightning luminaries for total luminous flux, efficacy, CCT, CRI, color coordinates and LID. Why to go for LM-79 Testing? If You are a manufacturer or vendor and want to sell your product in the market. Then you must be needed a test report of your product which will give all the parameters electrical and photometric measurement issued by an NABL accredited laboratory KC India LM 79 testing will give you a chance to improve your product by amendment in it if required. So, Testing LED luminaries are a necessary task to be performed in this competitive world. LM-79 Test Photometric Results: Colorimetric Parameters: Chromaticity coordinates: (Chroma x / Chroma y / Chroma u(u’) / Chroma v / Chroma v’) Correlated Color Temperature (CCT) Duv Value Color Ratio Peak Wavelength (nm) Half Bandwidth (nm) Dominant ...

 What Is LM  79 Testing (Lab)? LM-79 Testing Lab is an approved method for taking electrical and photometric measurements of SSL products. It covers total flux (light output), electrical power, efficacy, chromaticity, and intensity distribution. The five required metrics on the LED Lighting Facts label come from LM-79 Test Labs results. (IES)   Illuminating Engineering Society of North America Publishes LM 79-80 In 2008 Approved Methods for the Electrical and Photometric Measurements of Solid-State Lighting Products. Is also Know as LM 79 Testing ? LM-79 Testing captures performance characteristics of products that feature solid-state lighting (SSL) technology, including light-emitting diodes (LEDs). This testing provides a snapshot of performance under specified operating conditions at some point in the life of a product, usually at the beginning of operation— these are referred to as initial measurements. It does not address lifetime ratings, changing performanc...
