Határidő: Lamp Lumen Maintenance Factor

The Lamp Lumen Maintenance Factor (LLMF) describes the normal reduction of the luminous flux during lamp life. E.g.: factor 0.96 after 2,000 hours: the light output of the lamp after 2,000 hours is 96% of the initial light output.
"m" = operation with magnetic ballast / "e" = operation with electronic ballast.
