Table 17.Possible Performance Parameters for LED MEPS Criterion Description Why it is important Existing Performance Standards MEPS Levels Derived from IEA 4E SSL unless otherwise specified Claimed Equivalent wattage /minimum light output (lm) (retrofit lamps only) If equivalency is claimed to an incandescent lamp the minimum light output requirement ensures that the LED product produces at least the same amount of light (on average over its life) as an incandescent light source of a given wattage; These levels assist in evaluating manufacturer claims of equivalence for consumers choosing replacement lamps. Acceptable light output levels are of highest importance for safe working and living conditions.
