LM-79 is a testing report standard that describes a codified method to measure and report on the photometric performance of a solid state LED luminaire.
LM-79 considers absolute photometry of the led lighting luminaire, rather than relative photometry results such as could be calculated from various LED lighting components or LED lighting modules. Thus, LM-79 does not apply to led lighting products or LED lighting components that are categorised as LED Chips or LED lighting engines. Industralight LM-79 test reports provide key information on Industralight products including system power consumption (W), LED drive current (mA), CCT (colour temperature), luminaire efficiency and photometric distribution. The nature and requirement of an LM-79 report is such that a complete LED lighting luminaire is always submitted to facilitate LM-79 testing.
