Lumen maintenance
Lumen maintenance is the most useful gauge to determine the lifetime or useful light output rating of an LED light source. Unlike traditional light sources such as incandescent lamps, LEDs rarely fail outright and instead continue to emit light, albeit at slowly diminishing rate over time.[1] Lumen maintenance is the luminous flux remaining

LM79 Validation
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.
