Lumen maintenance is a step of the quantity of light produced from a light or luminaire when it is brand new as compared to the light output at a specific time in the future. Until now, lumen upkeep was often defined as L50, L70, L80, L90; or LM50, LM70, LM80 or LM90; with L or LM both standing for lumen maintenance and the number specifying the percentage of light output staying.
