What are the limitations of LM-79?

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.
