Definition of LM-79 Testing:
LM-79 is one approved method that describes procedures & precautions in performing measurement of LED products.
Scope of IES LM-79 testing:
LM-79 Testing is applied to solid-state lighting products that include the following requirements:
LED based products that are integrated control circuit and heat sinks
LED based products only requiring AC or DC power supply
And does not cover as bellow:
LED products requiring external operating circuits or heat sinks (bare LED chips, package and modules)
Fixtures designed for LED products but sold without a light source
Electrical Requirements:
SSL products work with AC power: voltage, electrical current, power, frequency, power factor
SSL products work with DC power: voltage, electrical current, power
Test Condition and Procedures/LM-79 Procedures and Conditions:
Ambient Conditions
Temperature–maintaining at 25℃±1℃ / Maintain temperature at 25 degrees C +/-1 degree C (within 1M)
Integrating Sphere: Integrating sphere systems are used to measure the total luminous flux and color for LM-79. This can be performed with a photometer (total luminous flux) or a spectral radiometer (spectral radiant flux). Utilizing a spectral radiometer and integrating sphere is the preferred method, which derives total luminous flux and color qualities form spectral radiant flux measurements.

Flux (to derive total luminous flux and color qualities)
Goniophometer:Goniophotometer systems are also used for LM-79 testing to measure luminous intensity distribution. The Goniophotometer system tests derive total luminous flux and provide color characteristics including CCT and CRI.
For measuring luminous intensity distribution
Total luminous flux is derived
Provides color characteristics with spectral radiometer including CCT, CRI
