LM-79 Testing
As the development of LED technology continues to grow and diversify, the need for consistent and standardized testing procedures for LED has become more prevalent than ever. ITC is a NABL( ILAC) accredited lab for LM 79 Testing
ITC India has made strides to stay current with the new testing standard LM-79 set forth by the IESNA (Illuminating Engineering Society of North America). In addition, "ITCIndia" testing is now a priority when testing our LED light systems for more reliable results. Fixtures tested by LM-79 standards will now feature a Lighting Facts label provided through the program created by the U.S. Department of Energy.

LM-79 Electrical and Photometric Measurements of Solid-State Lighting Products
Approved method describing procedures and precautions in performing reproducible measurements of LEDs:
Applies to LED-based products incorporating control electronics and heat sinks, that is, those devices that require only AC mains power or a DC voltage power supply to operate.
Absolute Photometry Basis
Relative vs. Absolute Photometry
LM-80 is there to help ensure that when a person chooses to purchase an LED that they are getting the most out of their new bulb. One interesting thing about LEDs is that they do not “burn out” the way traditional incandescent light bulbs do because they do not have a filament to burn out. With LEDs the light quality just depreciates to the point where the bulb is no longer usable. LM80 is the approved method for measuring lumen depreciation of LEDs. Simply put, LM-80 helps to validate that the bulb will have a usable amount of light for as long as it says it will.

LM-79 Electrical and Photometric Measurements of Solid-State Lighting Products
Approved method describing procedures and precautions in performing reproducible measurements of LEDs:
- Total luminous flux
- Electrical powers
- Luminous Intensity distribution
- Efficacy (lm/watt)
- Chromaticity
Applies to LED-based products incorporating control electronics and heat sinks, that is, those devices that require only AC mains power or a DC voltage power supply to operate.
Absolute Photometry Basis
- LM-79 requires complete luminaire testing
- Traditionally, photometric evaluation of lighting products is based on separate tests for lamps and luminaires
- For SSL products, LED lamps typically cannot be separated from their luminaire because of heat effects
Relative vs. Absolute Photometry
- Relative testing – Lamps of interest and luminaire are measured separately. Then the actual light distribution and intensity of the complete luminaire of interest is derived by normalization of the test data
- Absolute testing – The actual light distribution and intensity of the luminaire of interest is measured directly from the complete luminaire.
