As we all know about the strength of LM 79. Everything has its pros and cons. Let us have a look on the drawbacks of LM 79.
LM 79 depicts the parameters of the individual products. So the obtained Parameters cannot be used to access alike products.
Other limitation is the sample size. It does not state any sample size. So, the manufacturer provides only one sample instead of supplying more. This thus increases the vulnerability of lesser quality products.
This can be used only to determine complete luminary instead of LED used ( as based on absolute photometry) , which can produce different results due to quality of accessories used like glass, thermal effect, lenses etc.

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.

IES LM-79 Electrical and Photometric Measurements of Solid-State Lighting Products
Approved method describing procedures and precautions in performing reproducible measurements of LED Lights:
Total luminous flux
Electrical powers
Luminous Intensity distribution
Efficacy (lm/watt)
Chromaticity
LM-79 Luminaire Testing Scope:
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 (Relative)
For SSL products, LED lamps typically cannot be separated from their luminaire because of heat effects (Absolute)
Relative vs. Absolute Photometry:
Relative testing – Lamps of interest and luminaire (with reference lamp) 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.
